Intermittent problems with cPanel account authentication

[jedgtucker]

I manage a dedicated server with cPanel/WHM installed. A couple nights ago I noticed my email was no longer authenticating. I attempted to log in to cPanel and get

Internal Server Error


500


Could not fetch uid or gid for : netstuc8
cpsrvd/11.30.5.2 Server at mydomain.com


Then about a night ago it started working again, and then again stopped authenticating this morning. I haven't made any server configuration changes in months. I confirmed the netstuc8 user still exists in /etc/passwd, and resetting the password in WHM has no effect. My other cPanel accounts function just fine on the same server. I am out of ideas as far as what to try at this point. Any help would be greatly appreciated, thank you.

Hi,

Put the cPanel build in stable mode (if it is not) and then try /scripts/upcp --force. I hope that should solve this error forever.

Are you seeing anything in /usr/local/cpanel/logs/error_log location when you try to log into that account and have that error occur?

Next, what url are you using? Can you try the IP address for your server instead? I'm wondering if the domain is going back and forth between different IP addresses and sometimes it is hitting the other IP address that isn't your server's IP.

Cpanel is in stable mode and I ran /scripts/upcp --force but still have the same problem.

I am accessing the Cpanel control panel via IP, when I attempt a login, the error log records the following:

Internal Server Error: "GET /frontend/x3/index.html?post_login=53892526947626 HTTP/1.1" 500 Could not fetch uid or gid for : netstuc8

Hello

Are you sure that "netstuc8" is the correct username? That error message can sometimes be indicative of an incorrect username being entered. You can run the following command to check this:

# id netstuc8

If it is a valid username, you may want to consider opening a support ticket so we may check further.

Thank you.
