My website has a really strange and hard to reproduce error. Some users report that they get an ERR_SSL_VERSION_OR_CIPHER_MISMATCH. (if they refresh the page it seems to go away)
I’ve checked the Origin certificate and it is valid and working and the edge certificate and they both look okay.
The TLS version is set to version 1.2 and the TLS encryption mode is set to “FULL”
I have run qualys and returned an A+ rank.
So I think that everything related to the config of the site seems to be okay.
Does someone know if this might be a browser issue? Did someone had an error like this before, how did you solved it?
