Tin problem - reconnection always needed?

I've been using tin for years, and have never had a problem until now.

When I run tin and try to connect to my news server, it will connect  
and then almost immediately say:

Connection to news server has timed out. Reconnect? (Y/n) Y

If I answer Y, it will connect and keep doing the connect/reconnect  
in an endless loop or until I hit N.  If I set the option in tinrc  
for auto-reconnect, it will hang forever.

I am using tin 1.9.2, but have tried 1.7.5 and 1.8.3 and they are all  
having this problem.  I'm not sure how it started, but it seemed to  
come about when I tried installing v1.9.2.  Furthermore, this error  
occurs on any NNTPSERVER and it only occurs with tin.  I can use  
Sylpheed just fine, but I'd rather use tin.

I am running this on Solaris v9 in case that makes a difference.

Any ideas?

Thanks,
Joey
