"something went wrong" (horribly, losing a lot of work here)

[joglidden2]

Obviously this happens a lot. Rather than recreating my report from scratch and LOSING all of my work...

Should I wait and try again tomorrow? (this appears to be one common recommendation)
Do I send someone my 153-line error message? 
Is the latest version of PBI desktop a bad build, and should I wait until a new build is issued? (I have a few days)

I can view the report just fine in the service. If I 'download report (preview)' what I'm seeing in the service, I get the same "something went wrong", and the report will not load.

What other information can I provide?

Hi @joglidden2,

What type of operations are you worked when the error messages appear? It will help if you share the detailed error logs. (They may be caused by your operations or device environments.)

In addition, have your check the limitations of download report features. These may also cause the issue when your scenario meets the limitations.

Xiaoxin, thanks for the reply. It has not happened again. I re-installed PBI and rebooted. Then next day I was not having the problem, so my suspicion is it was a PBI server somewhere, possibly Azure. Once it happens again, I'll post the error log. Also, thanks for the links.

@amitchandak , thanks for the reply. The issue appears to have resolved itself, and now the report loads and renders. It must have been an issue with a Microsoft PBI server, where PBI desktop needs to communicate in order to work properly. 

Are you suggesting that error log indicates what and where the problem is? 

Also, is there a PBI website somewhere that indicates the health of servers and server operation? I can do this with Azure.

And it's doing it again. I'm beginning to think a re-install of PBI is in order. It appears to occur more frequently when I attempt to open a second instance of PBI Desktop. This makes me think there are memory-management issues with the code (something Microsoft is infamous for). Def gonna do a re-install.
