HTTPS ERR_SSL_VERSION_OR_CIPHER_MISMATCH

[MartinDoed]

Hi,

I was able to successfully to upload SSL certificates to my APCs (AP9631) created with NMCSecurityWizardCLI.exe. However when I try now to access via https I get this error: ERR_SSL_VERSION_OR_CIPHER_MISMATCH

Analyzing the traffic with WireShark I can see handshake failures:

Tried with different browsers and multiple APCs - any idea what could be the problem?

Thanks

Martin

Hi Martin,

From the pcap, it looks like the one device is expecting a TLS 1.2 response, and the other is giving a TLS 1.0. You can set the minimum protocol on the NMC to TLS 1.2 under Configuration --> Network --> Web --> Access
