No access to control panel after let's encrypt renew error

Hi there,

i do have a i-mscp 1.5 running with the let's encrypt plugin. I do use the let's encrypt certificate for my control panel.

2 days ago the let's encrypt certificate ran out of coverage. Now i'm not able to connect to my control panel anymore. I tried restarting the whole server. Now i do get the "internal server error 500" message.

Does anybody have an idea what to do in this case? Webmail / PMA etc. does have the same error.

Thank you guys in advance for your help!

Ok i was able to fix it.

The let's encrypt plugin didn't renew the certificate so i had to do it manually.

Due to this, the old control panel URL wasn't working.

With :8443 i was able to connect to the control panel.
