I have a problem consuming a WCF service through a silver light application, the problem suddenly happened today, the same piece of code was running successfully 1 month ago,
I got the following exception:
{System.ServiceModel.ProtocolException: The content type multipart/related; type="application/xop+xml";start="<http://tempuri.org/0>";boundary="uuid:22bb2c0b-5a1b-498d-9539-a19fa401d509+id=6";start-info="text/xml" of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 626 bytes of the response were: '

Content-Type: application/xop+xml; suggests that the wcf service is configured to use MTOM encoding on the server which is not supported by Silverlight.
I am not sure how this could have worked earlier unless there has been a change in the endpoint recently causing this error.

I am having issues connecting to the SoftLayer Product/Orders APIs.
Endpoints: Product_Packages is dropping the connection, Product_Place_Orders is returning invalid auth. Hardware and VirtualGuests are accepting the credentials and returning the information I expect.
Either:
Invalid credentials
Connection reset by peer
I am, however, able to use the same credentials to see what machines and vlans are in the account.
Looking into this more, curl works, another client I have works still, however the SoftLayer python client stopped working overnight.
Did the API change Auth mechanisms change last night?
import SoftLayer
client = SoftLayer.create_client_from_env() # or
client = SoftLayer.create_client_from_env(endpoint_url="https://api.softlayer.com/rest/v3/")
location_groups = client.call('Location_Group_Pricing', 'getAllObjects')
Output:
Unexpected error: <class 'SoftLayer.exceptions.TransportError'>
Traceback (most recent call last):

raise exceptions.TransportError(0, str(ex))
SoftLayer.exceptions.TransportError: TransportError(0): ('Connection aborted.', error(54, 'Connection reset by peer'))
catching the exception shows the following:
Unexpected error: <class 'SoftLayer.exceptions.TransportError'>
A working curl for the same endpoint:
curl https://<username>:<api_key>#api.softlayer.com/rest/v3/SoftLayer_Location_Group_Pricing/getAllObjects.json
Also verified that the Golang client works.
https://github.com/softlayer/softlayer-go
Just to point out that I am experiencing the same issue and I believe there is another post from someone else also mentioning the same transport/connection forcibly closed issue.
Worked last night, not working today. I'm changing my api key and user_name to see if it gets fixed. Note I too have multiple SL accounts. I'm swapping to my primary account API credentials to see what happens.
Here is the error

After talking with SoftLayer support, there was a service issue which has now been resolved.
Future Mitigation:
More extensive testing for older clients and related systems will be implemented into our Change Management guidelines to prevent this type of issue in the future.
(I like that part :)
This was an issue in Softlayer side, please try again it should be fixed now.
Regards
We don't have any report about issues for that, and I'm able to use SoftLayer_Product_Order service, could you provide your request(s)? for further assistance
How often have you been getting this issue?
Did you have success with those request before?
We have seen a noticeable uptick in problems related to RavenDB connections. We're using the IIS server connection method.
I've checked the index errors and I don't see anything listed.
This server is replicated with a MySQL server and there is one error related to replication in the log from today. Could the client stack trace errors actually be coming from the replicated server and not Raven?
EDIT
The client in this case is a single job that runs a few hundred times a day...succeeding many of those times but increasing in failures due to these errors.
Sql Replication failure to replication

The error says the client cannot connect to the the server. Maybe the client is offline. Or the server is. Or a firewall is in the way. Or maybe the server is there but blows up before returning a response to the client. If the issue is intermittent, and users arent complaining, it's probably just a connectivity thing that you can ignore. If users are complaining, you should look in server-side logs.
NServiceBus 3+ uses RavenDB for persistence by default. Several articles (this, this and this) mention that as long as RavenDB is used only to store NServiceBus data (Subscription, Saga, Timeouts), NServiceBus license is enough and separate RavenDB license is not required. However, the current version of RavenDB (Build 2700) doesn't allow the authentication to be setup on the server and throws below error (Cannot setup Windows Authentication without a valid commercial license). Does this mean that we can no longer use RavenDB (at least the latest version) with NServiceBus without a separate license? This works fine at least until build 2380. That is when the version is changed from v2.0 to v2.5. Using persistence without authentication is not an option as while Subscription and Timeouts are NServiceBus specific data, sagas can and do contain sensitive data that cannot be allowed to be accessible via http to everyone (even within LAN). Buying a license for RavenDB is not that big an issue but so far we understood that we only need NServiceBus license as long as RavenDB is not used for anything other than NServiceBus data. It would be great to get a clarification on this from NServiceBus or RavenDB team.

I added in the error I am getting on the server.
Is it possible I am getting this error because the service cannot write to the event log?
Please help.
Ensure that account running your process where the service is hosted has access rights to the database. For example in case of IIS the account running the application pool where the service is hosted must have login to database server and it must have permissions to do all necessary operations in your database.
Edit:
The server stack trace looks quite straightforward. You have a problem with writing to Windows Event Log! It cannot find source you requested and it doesn't have permission to create it.
I got the same error when I tried to use the following statement in a Web Method of a WCF Service:
string myTypeName = typeof(ErrorHandlerBehavior).AssemblyQualifiedName;
where ErrorHandlerBehavior derives from BehaviorExtensionElement.
The line works well when I test the service on my localhost. On the web, the call of the containing method raises the Exception "Access is denied".
In this case, I guess that the cause was that my IP does not allow the creation of a BehaviourExtensionElement in a Partially Trusted environment (my service is in a shared hosting environment).
Finally, I succeded following the first mechanism described at https://learn.microsoft.com/en-us/dotnet/framework/wcf/extending/configuring-and-extending-the-runtime-with-behaviors about Service Behaviors:
"Using an attribute on the service class. When a ServiceHost is constructed, the ServiceHost implementation uses reflection to discover the set of attributes on the type of the service. If any of those attributes are implementations of IServiceBehavior, they are added to the behaviors collection on ServiceDescription. This allows those behaviors to participate in the construction of the service run time."
I just modified the derivation (no other modification required):
public class ErrorServiceBehavior : Attribute, IServiceBehavior
{ ... }
and use the class as Attribute of my service:
[ErrorServiceBehavior()]
public partial class MyService : IMyService
{...}
No other modification required. Check the original sample at How do I create a global exception handler for a WCF Services?.
I am using a WCF client to consume a non-WCF SOAP 1.2 web service. When receiving a SOAP fault as shown below, I receive a ProtocolException instead of a FaultException. There are no problems with the communication binding and the request is being processed successfully. But I cannot access the fault error in my WCF client. Any ideas?

I would recommend using Fiddler to intercept the raw response. In these situations (interop), it's best to bypass WCF entirely and read the response message as it arrives "on the wire." Trying to debug a non-WCF fault or a deserialization error through WCF can only give you headaches. =)
Most often, looking at the raw response will point the problem out like a sore thumb.
I think the problem you're having is because the server returns a 400 HTTP response code. Apparently the bodies of messages with a response code other than 200 are not accessible to the Silverlight client.
If you had control of the server, you could modify it to send a 200 response code instead of 400, but if you don't have control of the server, you need to modify your client to accept response codes other than 200.
I found some instructions here to change the client to use an alternative HTTP stack. I had the same problem as you (but with HTTP response code 500) and this fixed the problem. All you have to do is add this code at the beginning of your Silverlight application (for example, on the constructor for the MainPage class):
bool registerResult = WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);
Is the method being called marked with the IsOneWay=true attribute in the generated proxy class?
If it is then there is no back channel for the SOAP fault to be received on but WCF can get it back some other way and this shows up as the ProtocolException. As far as I am aware you need to have IsOneWay=false to get a SOAP fault.
