Woohoo! 🎉
The instructions in the https://superuser.com/questions/278948/clear-cache-for-specific-domain-name-in-chrome/444881#444881 were not accurate, but they brought me close enough.
Here is the exact sequence of operations:
F12 --> Applications tab --> Storage --> Clear site data --> refresh login screen

Thanks everyone for your help!

BTW - did the agent print out anything? Which version of clearml-agent are you using?

Where do I see the agent print outs?
I am using an old version. It's a trains server of version 0.16.3.

RotundSquirrel78 , can you please check the webserver container logs to see if there were any errors

How do I check that?

Hi Sigal, beside the repeating "newer_available" error in the browsers console are there any other issue?

Here it is.

I can enter my user name but even the button underneath it is blank (see below). Once clicking it, the whole screen is blank as in the 1st image that I sent.

Yes, I am using the trains server. We never took the time to update it to clearml.
The version (according to pip freeze) is 0.16.3.

RotundSquirrel78 , try going into localhost:8080/login

Just below the filter box there is an option called Fetch/XHR

I clicked Fetch/XHR and got the following (after another reboot)

In the top left you have 'console' see if you get any errors

If not, can you provide the output of docker inspect trains-webserver ?

I did not upgrade anything and did not do docker pull.
I am having a temporary network issue . Will send the output of the “ docker inspect” as soon as I can reconnect to my server.

SuccessfulKoala55 , here is the output of "docker inspect trains-webserver" (attached).

I would guess so
sudo docker logs --follow trains-webserver

No other error messages but the dashboard screen is blank.
However, there is a breakthrough: I can run the dashboard from Safari (Mac browser). So the problem is only in Chrome.

Hi RotundSquirrel78 that indeed doesn't look right...What server version are you using? From the "t" icon it seems it's still a trains server?

Here is a snapshot of the blank screen:

Here is the developer tool Network screen capture after refreshing the page and trying to login.

Please filter by 'XHR' and see if there are any errors (any return codes that aren't 200)

I get an empty list for the 'XHR' filter.

Many errors :white_frowning_face: . Any idea what they mean?

RotundSquirrel78 did you upgrade anything or did docker pull by any chance?

Anyone? Please?

can you try the following https://superuser.com/a/444881 to clear the cache in chrome?

Please open developer tools (F12), go to the network tab and refresh the page
