Re: Error: Can't load SSL certificate

My suggests to look for:

1. Are your other servers setups installed from "Entware for QNAP" too?
2. Do your other servers have libz.so* located under /opt/lib/ too?
3. Did you compare owner and permissions of every libz.so* file between servers too?
4. Are other servers running Dovecot with same user account?

I try to logon to map using dovecot with SSL required. I get following entries in the log:Mar 20 13:49:30 auth: Debug: Loading modules from directory: /opt/lib/dovecot/modules/auth Mar 20 13:49:30 auth: Debug: Module loaded: /opt/lib/dovecot/modules/auth/lib20_auth_var_expand_crypt.so Mar 20 13:49:30 auth: Debug: Read auth token secret from /opt/var/run/dovecot/auth-token-secret.dat Mar 20 13:49:30 auth: Debug: passwd-file /opt/etc/dovecot/userdb:Read 1 users in 0 secs Mar 20 13:49:30 auth: Debug: auth client connected (pid=26120) Mar 20 13:49:30 imap-login: Error: Failed to initialize SSL server context: Can't load SSL certificate (ssl_cert setting): error:12800067:DSO support routines::could not load the shared library: filename(libz.so): libz.so: cannot open shared object file: No such file or directory, error:12800067:DSO support routines::could not load the shared library: user=<>, rip=192.168.117.5, lip=192.168.117.2, session= Mar 20 13:49:30 imap-login: Info: Disconnected: TLS initialization failed.

The library files exist in the include directory [/opt] # find . -name libz* -print

./lib/opkg/info/libzstd.control

./lib/opkg/info/libzstd.list

./lib/libz.so

./lib/libz.so.1

./lib/libz.so.1.2.13

./lib/libzstd.so

./lib/libzstd.so.1

./lib/libzstd.so.1.5.2

./lib/libz.a

Have the dovecot settings the same on other servers and it works, Dovecot is v2.3.18, installed from Entware for QNAP. Any help appreciated.
