Description

The code constantly performs new HTTP API calls even if they have failed. There seems to be no time in between requests and this essential performs an denial of service to the API. This has been observed using the web interface (meshtastic/web#361). At first sight on the code, there should be a delay / fetch interval but I did not observe such a delay in the browser app.

There should be some delay after failed request, ideally an exponential backoff and maybe even treat 4xx and 5xx differently. For 4xx response codes it is unlikely that retrying will help anything, so connection should stop. For 5xx response codes the API call can be retried after some backoff

Relevant console output

No response
