Recently I have noticed SAB throwing out an error. Details are:

ENGINE Error in HTTPServer.tick

    self._sslobj.do_handshake()
SSLError: [SSL: SSL_SESSION_ID_CALLBACK_FAILED] ssl session id callback failed (_ssl.c:661)

I have been using SAB for some time now, and cannot tie this error to anything specific that has happened. After a service restart all is OK for a few days. Then the error pops up again. Anyone seen this before?
I am running SAB on Debian 9, and use a LetsEncrypt.org certificate.

Which version of SABnzbd / sabnzbdplus?

Posted: **August 16th, 2018, 2:41 am**

I'm running SAB 2.3.4.
Python: 2.7.13
OpenSSL: OpenSSL 1.1.0f

Can you reproduce it?

Did you Google "SSL: SSL_SESSION_ID_CALLBACK_FAILED"? Anything interesting? For example https://stackoverflow.com/questions/105 ... id-callbac and http://eavesdrop.openstack.org/irclogs/ ... 6.log.html ?

The error is unknown to me and the SAB forum, so my guess is as good as your's

When this occurs, and I click on the SAB config cog I get the following error on the config page:
"Secure (SSL) connections from SABnzbd to newsservers and HTTPS websites will be encrypted, however, validating a server's identity using its certificates is not possible. Python 2.7.9 or above, OpenSSL 1.0.2 or above and up-to-date local CA certificates are required."

I am running Python 2.7.13 and OpenSSL 1.1.0f.

I issued new certs from LetsEncrypt.org using a 4096 bit private key (I was using 2048 previously). I now do not get the error from within SAB, but SAB still suffers from the same symptoms. After a service restart all is well again.

I am unable to reproduce the problem. It unfortunately just happens at random.
I had a look at the links posted, and have searched online. But I guess I am not savvy enough to understand what the articles are implying I should change, and am yet to find a fix.
