ssl_error_no_cypher_overlap with FireFox 34.0.5

Anonymous user · ‎2021-06-29

Hi all,

today I updated my FireFox to 34.0.5 and now I can not access my UPSs via https. FireFox Errorcode: ssl_error_no_cypher_overlap.

FireFox disabled SSLv3 cypher algorithm.

With IE v10 it still works and if you add these two lines in the FireFox config (enter about:config in the address bar):

security.tls.version.fallback-limit 0

security.tls.version.min 0

I think the apc web authentication has to be updated.

Re: PDU AP7900 Firmware SSL Incompatible With Latest Web Browsers

The only thing I can offer right this second is to enable SSLv3 and we'll be communicating more details shortly on what the plans are for various products in relation to the mainstream browsers starting to remove/disable SSLv3.
