PlotAPI may timeout for setups seen in real use

[eivindjahren]

The following error condition can seemingly be hit by users which have large setups:

We have seen this traceback in real usage:

None of the URLs provided for the ert storage server worked.

Could this be because observation loading is slow? I remember we once doubled the timeout of initializing dark_storage, because it spent a minute parsing some observation file.

Are you sure it is only for large setups ? I had a similar error message "None of the URLs provided..." when running drogon (and all other models), and I learnt from another user with the same problem it was related to a proxy setting in one of my startup files .bashrc or .profile, so when I removed that everything was fine.

Good point @tralsos . @eivindjahren do you think it is possible to distinguish ( and advice the users ) between a "real" bug and the proxy-errors? Now we are treating RequestError and TimeoutErrors the same way.

[eivindjahren]

I am not sure. I think we would require some assistance from e.g. @oyvindeide

[oysteoh]

@eivindjahren you have assigned yourself to this, do you know if it is still a problem? Is the current criticality high relevant?

[eivindjahren]

I will have another look at whether this is a problem on Troll, if it is I think I will have to unassign myself as I have no way of reproducing the failure.

[oyvindeide]

Tested this recently, and is still happening.

[eivindjahren]

This should be ~twice as fast now, but we will have to test with troll before we know for sure.

Just got confirmation that this is still the case
