CloudyHamster42 what's the trains-server version ?
hit ctrl-f5 (reload the page) do you still ge the same error? Is it limited to a specific experiment?
not limited to a specific case and also happens after reloading the page
its also having trouble saving things to the server it seems
It seems something is wrong with the server itself...
where is it running? could you restart all the dockers ? Is it running on your machine?
