Web console not working

Hi,
I am unable to use web console as it is giving a 504 gateway time out error again and again.
Screen shot attached.
even logging from my labs (f.cloudxlab.com ) is not working. I unable to run any commands . can you please help in resolving the issue

Neither Jupyter Linux console nor the web console are working. While running hadoop command getting java out of memory errors. Pl resolve these issues at the earliest so that we can smoothly work on the hands-on exercises

Hi @pavan_kumar1 and @Bhababhuti_Mishra ,
Sorry for the inconvenience, some class was running which caused f.cloudxlab.com to slow down.
We have increased the memory of f.cloudxlab.com to same as e.cloudxlab.com. But while we were doing so, the machine had to be restarted and therefore there was a downtime.

Thanks
