I have deployed a .NET Core API on Nginx server on Linux. My API internally calls third party API using HTTPClient.PostAsJsonAsync method.
System is working fine in normal load, but in case of heavy load i am getting below error.

Can any one help me to solve this?

I am running into a problem that, Azure DevOps runs without a problem when I trigger manually, but throws error when it runs automatically.
The error is about SSL certificate verification. I use self signed certificate, but I set up the configuration and gave GIT_SSL_NO_VERIFY = 1 in pipeline variables.
It must work with this configuration and works when run by manual trigger. But it is giving error when it is run by automated process. Error is:
An exception occurred while polling the repository. Error: Microsoft.TeamFoundation.Build2.Server.Extensions.ExternalConnectorException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

Is this a bug of Azure DevOps, or am I doing something wrong?
How can I narrow down what is causing this error to occur? There is nothing more in the stack trace or exception that I'm able to use to narrow down the problem.
This is happening within a docker container built on docker tag sdk:5.0 and running on aspnet:5.0. The container is running on Ubuntu 20.04.2 LTS.
It seems to happen when starting to run low on available host memory.

i keep having the same problem for a few weeks now and i can't seem to figure out what it is.
I recently stared using RavenDB and it was working fine, but after a few days when i come home and want to boot the server on my local machine it just does not want to boot, it gives the following stack trace in the logs:

Now i am not very familiar with networking but i have no clue why initially it works for a few days and then it just stops working.
Any help would be greatly appreciated.
The most likely reason is that there is something that is already using the port that RavenDB is trying to bind into.
Check things like Get-NetTCPConnection output or netstat to verify that

Service work only if i start service from VS2010 (project->debug->start new instance).
"Service work only if i start service from VS2010 (project->debug->start new instance)."
Sounds to me like you haven't actually hosted the service anywhere outside of Visual Studio. Based on the service endpoint address it's looking for, it looks like your intent is to host under IIS.
You'll need to configure IIS with a virtual directory/application for the service.
How to: Host a WCF Service in IIS
The error message says that it cannot find the service at https://localhost:44300/DataService.svc
This is probably the address where VS runs the service.
If you have installed the service anywhere else, for example on port 80, the client cannot find it because the client is looking on port 44300.
I'm new to WCF and have not much idea. By using a sample code I tried WCF through remoting...
It works fine for few min but if i leave the client without accessing the WCF server I get an exception like this....
Exception:Unable to connect to the remote server.

But it's not in faulted state nor it's closed!!!
Actually in my application the client communicates to the server which in turn contacts the WCF and gives him the work to do....
Right now I'm using Cassini as my server. It works great for few min but after nearly ten min it just shows this error message.... but if i restart my Cassini it works properly for few min again and gets the problem....
I cant understand how it goes to faulted state when it's able to connect more clients....
is it because the session has timed out or what? and if session has timed out then from which side from my server or client???
Any Idea plz..........
I've been siting with it for whole day but could not trace out any thing!!!
It may be a timeout problem, related to when you create the wcf proxy object in your client code.
It looks like you create the proxy object when you start the client and then just reuse it. This object maintains a connection to the server, which timesout after 10 min.
A better way to do it would be to create a new proxy object with a using statement, each time you need it.
" if i leave the client without accessing the WCF server I get an exception like "
May be due to inactivityTimeout, so you can increase it, or dispose your client object as soon as possible (try using statement)
you can set the property as follows
<reliableSession ordered="true" inactivityTimeout="00:00:05"
enabled="false" />
