Suddenly my nordvpn through openvpn on my raspberry pi isn't working anymore. Now I get the following error:

No idea what to do. I can't find any server log. Tried removing and reinstalling. Tried updating. I can connect to the internet. It's just when I try to connect to a OVPN file it does this in a loop. I can even give a wrong login information and it won't say anything. Can anyone shine some light on this? Thanks
I've set up pfsense to manage my network, and I have the ACME plug in installed. I'm to correctly direct traffic to my secure webservers, but first I need to get the certificates onto PFSense.
At the moment, my certificates are using certbot on the webservers, but I want pfsense to manage all the certs.
When I use the stand alone method for the ACME plugin, I get this error, and I'm not sure where I went wrong in setting up pfsense. If someone could help me out, it would be great, thanks.

My problem was with AAAA DNS record. Ipv6 record pointed to another host.
Try to using ssh connect google cloud computer engine (macOs Catalina)
gcloud beta compute ssh --zone "us-west1-b" "mac-vm" --project "mac-vm-282201"
and get error
ssh: connect to host 34.105.11.187 port 22: Operation timed out
ERROR: (gcloud.beta.compute.ssh) [/usr/bin/ssh] exited with return code [255].
and I try
ssh -I ~/.ssh/mac-vm-key asd61404#34.105.11.187
also get error
ssh: connect to host 34.105.11.187 port 22: Operation timed out
so I found this code to diagnose it
gcloud compute ssh —zone "us-west1-b" "mac-vm" —project "mac-vm-282201" —ssh-flag="-vvv"
return

I don't know, how can I fix this issue.
Thanks in advance!

I recently purchased a cloud VPS service.
I've configured my website everything on that front is fine and well, however I noticed email isn't always being received.
Having inspected the log at: /var/log/maillog
I can see the following:

The email is successfully received on my personal Google email address, but the other order confirmation isn't received on the business email side (which is hosted by Google Apps)
I can also see for some reason the email apache#mywebsitedomain.co.uk is being used... When really I guess this should be info?
Could this be the reason I am not receiving emails or am I missing the plot here?
Any help would be greatly appreciated as always!
EDIT
I tried the contact form again and this now no longer works, I have a feeling because I haven't changed my live DNS of the domain to the new server. Google feels I may be spoofing the email address? But I did alter the SPF record to include the new server IP (would this not be enough?)
This was resolved by simply installing and switching to postfix (Credit to Rocket_Doge_) for helping me with this!
We´re using apache (2.0, with ssl) to proxy the requests to a web service installed on weblogic. We have mod_wl.so installed, and all works fine with small requests.
However, with larger requests (say, 300 KB), the apache stalls and display this error message:
"Failure of server APACHE bridge: No Backend Sever available for connections": timed out after 20 seconds or idempotent is set to off."
We replicate the scenario in another server, and the error persists (instead of "20 seconds", it says "30 seconds" for the same request).
How can I avoid this size limitation? Is it a bug in mod_wl.so? Is it a config value that is missing? (As a side note, the web service works fine when tested directly from inside the weblogic console, no matter how big the file)
Thanks for any help!
UPDATE:
changed to mod_wl_20.so with same results, here is the chunk of the log:

This is the WebLogic which Apache is trying to post to.
You have confirmed this works when directly posted to the same Weblogic server.
The 20 seconds mathces the default KeepAliveSecs which you can try to increase.
Have you set a value in the plugin for WLIOTimeoutSecs.
This defaults to 300. Defines the amount of time in seconds the plug-in waits for a response to a request from WebLogic Server.
But from your log it does not look like Apache is waiting for 300 seconds before failing.
Similarly MaxPostSize defaults to -1, just check that you have not set some low value for that.
