Heimdall unable to connect to Bor on WebSocket

[SimonKraus]

Heimdall is not able to connect to Bor via WebSocket.

Environment:

• OS: Ubuntu 22.04.3 LTS
• Install tools: Both software build from source on latest tagged release.

What happened:
Since updating Heimdall to v1.0.5 and Bor to 1.3.1 we faced a problem that Heimdall wasn't able to connect to Bor anymore and crashed on startup.
We fixed it by configuring an HTTP connection instead of WS.
The error message was:
2024/05/10 09:29:04 dial tcp 127.0.0.1:8546: connect: connection refused

What you expected to happen:
Expected to work (like before the update).

Have you tried the latest version:
yes

How to reproduce it (as minimally and precisely as possible):
Setup Heimdall and Bor and pair it through WS.

Logs (paste a small part showing an error:
2024/05/10 09:29:04 dial tcp 127.0.0.1:8546: connect: connection refused

Config (you can paste only the changes you've made):

# RPC endpoint for bor chain
bor_rpc_url = "ws://localhost:8546"

changed to:

# RPC endpoint for bor chain
bor_rpc_url = "http://localhost:8545"

Anything else we need to know:
Bor websocket is functional as other services use it through that port.
