Pjproject Sporadic (?) SSL error

Getting this error in the log. Can’t tell when or why but doesn’t seem to be all the time.

Jan 23 22:46:10] WARNING[3937] pjproject: SSL SSL_ERROR_SSL (Handshake): Level: 0 err: <336130204> len: 0 peer:

Asterisk version?

version 16.28 but I think I may have found the problem. I believe I may have had an incorrect cipher specified by the “cipher=” directive in pjsip.conf. It worked but spewed the error once in a while. Used SSL Server Test (Powered by Qualys SSL Labs) to find the best cipher. We’ll see…

If the error continues you should try ver 16.27.0 to see if it makes a difference.
16.28.0 (and newer) has a new TLS wildcards feature which I had a problem with also.

The warning occurred again. I took a closer look and now believe it to be a bona-fide warning. A closer look reveals the IP address to be a foreign one. Since we are running tls it smells like a scammer may be trying to hack in and tls says no-no. I’ll let it run a few days and see if the IP changes if it happens again.
