Beacon tries to reach https://goerli.infura.io over port 80, failing

[yorickdowne]

• Nimbus beacon node v0.5.0 (da3102c)
• Dockerized environment, buster-slim
• Remote goerli.infura.io accessed via https://
• beacon_node configured for testnet spadina

Beacon will fail to establish connection with infura. Logs show that it tries to reach it via 80, although URL is https://

The same failure is not observed when configuring testnet medalla.

Since the HTTPS endpoints of Infura are not currently supported, we are now automatically rewriting such URLs to their WebSocket counterparts (i.e. wss://). Thus, it's no longer possible to reproduce this issue. The lack of support for HTTP(S) web3 providers will be tracked here:
