Network related exceptions in package:gotrue/src/fetch.dart

[lukasnevosad]

Describe the bug
This is the same bug as described in #147 only in I am on server and using Supabase Dart (not Flutter)

I am sometimes logging dozens of warnings per second originating in package:gotrue/src/fetch.dart. These include:

• ClientException: Connection closed before full header was received, uri=https://xyz.supabase.co/auth/v1/token?grant_type=refresh_token
• ClientException: Broken pipe, uri=https://xyz.supabase.co/auth/v1/token?grant_type=refresh_token
• ClientException: Connection reset by peer, uri=https://xyz.supabase.co/auth/v1/token?grant_type=refresh_token
• ClientException: Write failed, uri=https://xyz.supabase.co/auth/v1/token?grant_type=refresh_token

with Stack trace:

"stackTrace": [
    "#0 GotrueFetch._handleRequest (package:gotrue/src/fetch.dart:179)",
    "<asynchronous suspension>",
    "#1 GotrueFetch.request (package:gotrue/src/fetch.dart:130)",
    "<asynchronous suspension>",
    "#2 GoTrueClient._refreshAccessToken.<anonymous closure> (package:gotrue/src/gotrue_client.dart:1079)",
    "<asynchronous suspension>",
    "#3 RetryOptions.retry (package:retry/retry.dart:131)",
    "<asynchronous suspension>"
  ]

The retry eventually succeeds it seems, as I don't see any related client errors logged.

To Reproduce
Happens sporadically, does not seem to be related to any client request
