We'll be looking into this shortly. 🙏🏻

@emielsebastiaan AFAICT it is consistently failing with:

[graymatter] 
GrayMatter has encountered an unrecoverable error and crashed.

  Error: Fuzzer failed: {:error, :eacces}

I guess either pyjamaz sets some weird permissions to the socket or it might be some server/docker misconfiguration, so please let me know if you'd like to test something.

Yes thx probably Monday.
