IHC communication issue


Have removed TLSv1 and TLSv1.1 .But still have issues . any suggestions ?

Rebooting both Pi and controller solved it

Update: No handshake problems ,but some communication issue stil exist.

Setup is a PI 4 ,with Openhabian and Openhab 3.2M3

i am getting error messages ,and cant control the IHC controller .

These are the current messages. not sure where to start

Very weirdly it just started to work after 5 reboots and waiting 3 days.

unfortunately , i do seem to have communations issues ,since i cannot control my IHC controller any more.
I would appriate any inputs towards solving this.

Same errors as above .
