websocket_api script: Error executing script

[jalohax]

I have tried to use this integration already few times, and all of them has failed.
Today I had some more time so I tried to gather some logs.

How the setup is made as for now:

• router is TP-Link MR6400
• v5.3
• as I found in few places for testing purposes router and HA are placed in same LAN (same IP pool),
• local management is allowed via port 80 (no any IP whitelisting),
• from same source (if I address PC to HomeAssistant IP for tests) I am able to login to TP-Link portal
• during testing I am logged out of the gui (as it was reported to interrupt tp-link API)
• I have droppped packets from tp-link facing port and packets from HA while calling notify service are visible

But the service falls by itself, I can see errors:

Looks like differences in router fimware / hw version.

Mine is:
Firmware Version:1.11.0 0.9.1 v0001.0 Build 200325 Rel.56677n Hardware Version:TL-MR6400 v4
