Recently on our server (not updated for, well, quite some time ) DA stopped working returning the following error when trying to start:

root@snickers:/usr/local/directadmin/custombuild# service directadmin start
Starting DirectAdmin: /usr/local/directadmin/directadmin: error while loading shared libraries: cannot open shared object file: No such file or directory

System is 64bit and has not been updated recently:

root@snickers:/usr/local/directadmin/custombuild# cat /etc/debian_version
root@snickers:/usr/local/directadmin/custombuild# uname -a
Linux snickers.xx #2 SMP Thu Aug 25 16:40:22 UTC 2011 x86_64 GNU/Linux

Yes since few days it started complaining about missing libs.

root@snickers:~# ldd /usr/local/directadmin/directadmin => (0xffffe000) => not found => /lib32/ (0xf775f000) => not found => not found => not found => /lib32/ (0xf7738000) => not found => /lib32/ (0xf75f0000)
/lib/ (0xf779a000)

DA error logs contains only one line, quite in line with the moment when the issue started occurring:

root@snickers:~# cat /var/log/directadmin/error.log
2018:04:16-00:36:49: *** Program Update: Request From which is not one of the certified update servers

Of course attempt to symlink 64bit ssl libs to /lib32 fails miserably.
License is set correctly, for Debian 6.0 64bit and even though it is not supported anymore (no more updates) it should work just fine (allegedly).

Any thoughts on that?
