SOLVED [CPANEL-27695] Failed to show template error400 in login theme

[bloatedstoat]

Anything to worry about? Is there a solution? Some of our logs are full of it.

We're on CLOUDLINUX 6.10 v78.0.24.

Thanks!

Hello,

To update, internal case CPANEL-27695 was opened to report an issue where errors like the following are logged to /usr/local/cpanel/logs/error_log upon connection requests to port 2087 that cpsrvd is unable to interpret:

Failed to show template “error400” in login theme “cpanel” (); falling back to legacy login. at /usr/local/cpanel/Cpanel/Server.pm line 2079.

file error - templates/error400: not found at base/show_template.stor.pl line 133.

I'll monitor this case and update this thread with more information at it becomes available.

Thank you.
