M

Martin_Berlin

New Pleskian
Product: Plesk Onyx 17.5.3 Update #22 Linux

I get these errors (see below) when I add a new Domain or when I renew Let's Encrypt Certificate

I did this but it didn't help:

Please help!
Thanks

Hi Martin_Berlin,

pls. consider to add corresponding log - entries from your "panel.log", as the Plesk Let's Encrypt Extension and Plesk log their actions there.
In addition, pls. consider to add as well your current used operating system. :)


Additional informations:


Sometimes, it is as well a good idea to change the log - level ( TEMPORARILY! ), to get more informations in Plesk - log - files:

 
Hi UFHH01,

Thank you for helping.

My operation system is Ubuntu 16.04.3 LTS‬.

I followed your advise and enabled:
; Enable logging of SQL queries
show.sql_query = on

I reproduced the error by renewing a Let's encrypt Certificate and got again this error displayed in the panel:
Code: 
Internal error ;-P
<html>
<head><title>502 Bad Gateway</title></head>
<body bgcolor="white">
<center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx</center>
</body>
</html>

But there where no entries in
/usr/local/psa/admin/logs/panel.log

I think the renew of the Certificate works as it's displaying
"Information: Let's Encrypt SSL/TLS certificate has been installed on..."
When I go to the startpage again.

The error says something about nginx - but the
/var/log/nginx/error.log doesn't show anything.

Do you've got any other idea?

Thanky you!
 
Hi Martin_Berlin,

actually, the statement:

Click to expand...
... is actually not very clear here. Do you mean, that Plesk didn't log the Let's Encrypt actions?

In addition, pls. note, that the DEBUG - LEVEL - mode for the Plesk Control Panel has to be set with:
Code: 
[debug]
; Enable debug mode (do not use in production environment)
enabled = on
... inside the file "/usr/local/psa/admin/conf/panel.ini" Pls. consider to read again: => How to enable/disable debug logging in Plesk Onyx and earlier versions for Linux? for further informations.

Would you mind to post the exact error message, as "The error says something about nginx" is unfortunately not very precise. :-(


Did you as well CHECK, if the new certificate has been installed for your (sub)domain? And if you checked it, could you tell us HOW your steps were to check it?
