Hi All,
When I am accessing WLC 5508 via GUI (HTTPS), I am getting ERR_SSL_VERSION_OR_CIPHER_MISMATCH. Further, the error details say "Unsupported protocol - The client and server don't support a common SSL protocol version or cipher suite."
The SSL error is observed only in Chrome and MS Edge only. However, I can access the same link in Firefox.
Can someone please share why such an error and how to fix the error?
Thank You
Shiv

- Probably because the 5508 used too old and or weak ciphers, what is it's software version ?

Did you find a solution to this issue?

No, in my case I think I will have to update the Aironet from version 8.4 to version 8.10.151, I really don't know if I have to follow any update path or if I can update directly to the new version

No, not yet. I believe WLC 5508 needs a software upgrade and it should resolve the issue. Any thoughts?
