Intouch http and https connection attempt fails with code SSL_ERROR_NO_CYPHER_OVERLAP

Product Discussion InControl

Hello,

having a setup where i need to make intouch connections available for users of incontrol2.

There is a webserver in the networkable to do both http and https.

Trying with https im getting SSL_ERROR_NO_CYPHER_OVERLAP error - would this be the server not having any cipher algorithms available?
Trying with http im getting the same error!! Which i guess should not happen, bcs http is not TLS’ed i.e. not using any ciphers. Where in Incontrol/Balance router does this translation happen?
Trying the “oldfashioned way” with portforwarding - i can get through to the server instantly - so server is working.

I have tryíed copying the setup with a BR1 and a small webserver in my office. Here everything works smoothly.

So where is my problem lying? Anywhere in Incontrol its possible to steer http into https which i should need to disable?

You’re seeing SSL_ERROR_NO_CYPHER_OVERLAP likely because the server is using outdated or unsupported SSL/TLS ciphers that modern browsers reject. For HTTPS, ensure the server supports protocols like TLS 1.2 or 1.3. For HTTP, this error shouldn’t happen, as it’s not encrypted, so something may be forcing HTTPS, either on your server or via InControl2 settings.

In InControl2 (Peplink), check under “Remote Web Admin” or “InTouch” settings if there’s an HTTPS redirect or SSL enforcement rule. Disable any forced HTTPS and test again. Also, ensure your Balance router firmware is current, as older versions may mishandle SSL/TLS negotiation. If port forwarding works but InTouch doesn’t, the issue lies in how InControl2 wraps and redirects the connection.

Let me know which Peplink model and firmware version you’re using?
