dovecot - Dec 2019 - Error: proxy: Remote returned invalid banner: 220

I had a working proxy setup added sieve to it, and out of the blue I get 
this

Error: proxy: Remote returned invalid banner: 220 

No idea what to do, nothing even in the mail list archive

With a telnet to port 110 on the proxy

Looks a lot like you're mixing up protocols, but I need your 
configuration to confirm (output from `dovecot -n`).

Regards,

Stephan.

I started over and ended up adding this 
homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid to 
the pass_attrs ldap entry. Now the proxy seems to work. 

pass_attrs = 
uid=user,userPassword=password,host=host,homeDirectory=userdb_home,uidNu
mber=userdb_uid,gidNumber=userdb_gid
