MAC Check Failed

[hateriarch]

I have started getting this error and it is preventing men from plotting. I have tried a few things to clear it up but nothing is working. I tried a new set of keys, I tried move the .chia dir and letting it resync. Below is the error. Any help will be appreciated.

I have exact same problem. Have you found a soultion?

[potato1992]

same, ubuntu 20.04, newly install. 1.5.0, can you just stop writing garbage code?

That was happening to me during that time when everyone was having problems syncing. I updated to the hotfix and it went away.

Haven't seen it since

not working for me :(

Fresh install, Debian 10.9 headless. Was working until I rebooted the system.

If you are still experiencing the issues it is recommended to upgrade to the latest version of chia. Please download it from here: https://www.chia.net/downloads/

Since this issue has been open for a number of years without additional comments, 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

The best place to reach our support team is on Discord (https://discord.gg/chia) or by reopening this ticket.
