Dear experts,
running paraview with **–multi-servers** option generates a fatal error if user opens a file, after disconnecting from a server.
the issue can be reproduced as follows:
- in a terminal, start **pvserver**
- in a second terminal, type: **paraview --multi-servers**
- in the main menu bar, click on connect and connect to server
- in the pipeline, select the server and click on disconnect
- in the main menu bar, select File - Open
**==\> Paraview crash.**
Digging this out, it seems that in method **pqLoadDataReaction::loadData()**
`pqServer* server = pqActiveObjects::instance().activeServer();`
returns NULL which leads to the crash.
Replacing :
`pqServer* server = pqActiveObjects::instance().activeServer();`
with :
`pqServer* server = pqApplicationCore::instance()->getActiveServer();`
seems to fix the issue which can be reproduced with Paraview 5.9
Thanks.

I’m curious why you are using the `--multi-servers` flag if you are only connecting to one server?
Not trying to be a jerk, just wondering if there’s some kind of functionality I’m unaware of 🙂
I just started using this flag myself but always with the server.

Hi,
apologize, but do you know the status of this bug report?
Nabil (strangely, I can not use the double authentification with my Github account on Paraview.
It seems that the Two-factor authentification does not really work for Paraview Discourse.

nothing happened yet, first an actual issue would need to be created:
