We have recently come across the "
TLS Cipher mismatch" error as well on our WS-12-250-AC switches using 1.5.9rcX when logging into them using Chrome version 98 and FireFox version 96. It seems to be involved with the switches using a deprecated version of SSL/
TLS, but I understand that you are working on a fix as mentioned in a previous post. I attached a screenshot below from FireFox showing the "SSL_ERROR_UNSUPPORTED_VERSION" error.
Our temporary workaround is to change the "security.
tls.version.enable-deprecated" setting to "true" on FireFox from the about:config page, but we cannot seem to find one for Chrome or Edge in any of its Internet settings, so this may eventually restrict remote access to our switches soon if these browsers do not allow older verisons of
TLS. Is there an update on when this will be fixed?
