Connecting to Wallet, Script ../chia/daemon/server.py Fails, OS Error:99

[konuralpilim]

Chia GUI on Ubuntu 20.04.2.0 is stuck on "Connecting to Wallet" screen. GUI started from command line gives the following errors:

Developer tab from Chia GUI gives the following errors:

Uncaught Error: connect ECONNREFUSED 127.0.0.1:55400

Areas of interest may be the following I guess:

server = await self._create_server()
  File "/usr/lib/python3.8/asyncio/base_events.py", line 1463, in create_server

Uncaught Error: connect ECONNREFUSED 127.0.0.1:55400

Can this be fixed on the user's end? What can I do to make it work?
Thank you.

@konuralpilim , the newest version(s) of chia has fixes in place to resolve this issue. Please download it from here: https://www.chia.net/downloads/

Since this issue has been resolved with the latest version(s) of chia we will be closing this ticket but if we have closed this ticket in error do not hesitate to reach out to us again with any followup questions, comments, or if the issue persists after an update.

Please note that upgrading major versions of chia generally requires the config.yaml to be recreated using these steps:
1. Stop chia
2. Rename the config or move it to a different directory
3. In CLI run chia init
4. Copy any custom settings from the old config to the new (plot drive directories, pool info, trusted node info, etc) - be careful here as yaml is very picky about formatting including those leading spaces
5. Start Chia
