This is a posting to help anyone experiencing a seemingly random SSL error with Secure Connect.
If you receive a message something akin to the following on the Secure Connect client, all you need to do as a workaround is to run 'restart web-management'.
Configuration Download
Login: HTTPS request failed.
OpenSSL SSL_read:
error: 1408F10B:SSL
This is being experienced with the recommended Junos v22.4R3-S2.11
It is regrettable how dependant Secure Connect seems to be on J-Web, essentially. Incidentally, you'll notice if you experience the above that you cannot access J-Web.
