No idea, all our servers have plesk on it. It never happened till now, only started happening with the latest plesk version.
It did happen on a centos 6 that was terminated by the client and upgraded to the latest plesk, but because it was centos 6, i didn’t pay a lot of attention to it at the time because centos 6 is eol and we are upgrading all servers to centos 7 anyway.
As GDPR law dictates, the disks of that server are cleaned so i can’t look at it to see if it was there to.
This server was/is a test to learn the new plesk, but that version is not yet production ready for several more months in my book. Plesk says it is, but reading there forum and seeing what errors they fix in there updates, i say it is not.
Duh, then there might be something else. Probably some Perl modules incompatibility. It would require more digging. I am not sure if it’s worth further time investments, though.
If i would guess i would say that plesk changed pam_plesk.so. I remember reading that in plesk 18 tls 1.3 was added for OS’ses that support it. Perhaps thats why they changed pam_plesk.so.
Changing to the old one works, so i connsider it fixed. I am going to set up a “file change monitor” in case plesk changes it again.
I have the same issue. Please + Webmin. If I disable SSL for webmin it works.
/etc/init.d/webmin restart
Stopping Webmin server in /usr/share/webmin
/etc/webmin/stop: line 4: kill: (19050) - No such process
Starting Webmin server in /usr/share/webmin
Failed to create SSL context : Invalid argument at /usr/share/webmin/miniserv.pl line 4381.
The solution is hidden in this post, ill summerize and give my sollution how to fix it forever and ever. The problem is that plesk always changes the file again, so you have to be prepared.
create a test file test under “System and Server Status” File, directory or pattern to check = /etc/pam.d/webmin Size must be smaller than = 120 bytes If monitor goes down, run command = cp /etc/pam.d/webmin.ok /etc/pam.d/webmin
every time plesk does an update you will get a mail that webmin has replaced the plesk faulty one with a correct one.
