Hi. When I go to Extensions, I get this error:
Internal server error Retry

I don't know what is wrong...

Thank you
 
Try to run on Plesk server following command:

Code: 
# wget https://ext.plesk.com

Do you see any certificate related errors?
 
wget Plesk Extensions

Result:

Are you sure that command was correct? It should be

Code: 
# wget https://ext.plesk.com
 
wget Plesk Extensions

Try to remove extension catalog cache with following commands:

# rm -rf /usr/local/psa/var/cache/https*
# plesk db "delete from PersistentCache where events like '%catalog%'"
# service sw-engine restart

mr igor, I don't have extesions, why is it returning the following error when I run the command?

[root@*****~]# wget Plesk Extensions
--2021-10-06 14:44:22-- Plesk Extensions
Resolving ext.plesk.com (ext.plesk.com)... failed: Name or service not known.
wget: unable to resolve host address ‘ext.plesk.com’
 
FYI Guys, if you already tried all these things and the issue persist, Check:
Code: 
Date
On the server. I was fighting with this and the issue was solved by updating the date and time on the server. In this case, to apply an easy fix I ran the following:
Code: 
ntpdate 0.us.pool.ntp.org

I hope helps someone. :)

Worked for me. I got into the issue after installing Plesk Obsidian 18.0.59 (from Plesk Obsidian 18.0.55) today.

Then i removed "Plesk Email Security" and after realizing was not the cause of Resolved - Arc errors in maillog i tried to reinstall.

I clicked on "Plesk Email Security" (from catalog) but the browser returned back (nothing happen)

Going directly to the extension link DOMAINNAME:8443/modules/catalog/index.php/catalog/package/email-security i notice the "Internal Server Error" message.

PS: wget https://ext.plesk.com was working fine .. but didn't solve the issue.

I think this is normally a bug into Plesk and should be fixed ..

Thank you!
