Error launching monitoring using UI

stephenw10

Hmm. And, just to be clear, you are no longer seeing it after adding the server?
Are you able to test removing the server? I expect it to still work in that situation. Errors like that are almost always because nothing has ever been configured.

I see quite a few places in the code on that page where it could have issues with PHP 8.1, though I haven't managed to replicate any errors yet here either.

I have an update pushed which should take care of any potential PHP 8.1 issues I could find in the code. It should start showing up in builds tomorrow.

If I remove the instance of the server, I get my error back:

PHP ERROR: Type: 1, File: /usr/local/www/status_monitoring.php, Line: 287, Message: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/status_monitoring.php:287

Ah, interesting. Well now you can try the above commit via the System Patches package if you wish. or just wait for the next snapshot.

@stephenw10
great, thank you very much @stephenw10 and @jimp!
I will install a new snapshot in the morning and report the result.

@jimp and @stephenw10 - you are the best!

The original Monitoring error issue is gone - tested with and without the OpenVPN server being defined.
Now I'm faced with another issue - OpenVPN service fails to start. Tried nuking and re-creating the server as UDP only and as TCP only, made sure the firewall rules have been created. No dice.

The only thing that makes mike installation different from "vanila" is dual gateway setup, but that should be completely transparent, no?

stephenw10

Indeed, dual gateway shouldn't make any difference.

Do you see errors in the system or openvpn logs?

Ok, so the issue seems to be an empty cert file:

Any idea how to force the cert to be regenerated?

stephenw10

Make sure the cert exists in the cert manager (System > Cert Manager). If not create a new one there and then edit the OpenVPN instance to use it.

yuryk

That worked. For some reason, when I initially told the setup to create a new certificate, it just created a private key and not the certificate. Jan 24 build however worked!
