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!

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

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

Here it is.

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

How do I check that?

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

Anyone? Please?

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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.

RotundSquirrel78 , try going into localhost:8080/login

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.

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:
