When Using Cloudflare tunnel with a Multi Level Sub domain IE

Plan.MC.Server.tld

You may end up with an error of "ERR_SSL_VERSION_OR_CIPHER_MISMATCH"

Troubleshooting Steps:

1. Wait for a few hours to make sure its not a delay in certificate Activation (up to 24hrs)
2. Make sure the domain is showing as proxied (Orange Cloud) in DNS Settings, under CNAMES, Tunnel should do this automatically
3. If you use custom certs, make sure its not expired

Fixes:

Free

Cost

B) Get an advanced or custom certificate
C) Use Cloudflares Advanced Certificate Manager
