App freezes when no connection available

[dv0vd]

Describe the bug
Sometimes my Internet connection interrupts. My WiFi is still on, but my computer can't connect to the Internet due to problems with my Internet provider. If I start the app during this time and try to open a project it just freezes. Also, this happens if I deny Internet access via opensnitch. In the logs, there is an error: ERROR version: Failed to get version from: http://www.openshot.org/version/json/. If I open the app when my WiFi is off - everything all right.

Steps to reproduce the behavior:

1. Disconnect the ethernet cable from your router or deny Internet access to openshot using opensnitch
2. Open the app and open a project or open your .osp file directly
3. See app freeze

Expected behavior
Open the project with active connection, but without the Internet connection without any errors.

Please try the latest dev daily build of v3.0.0 and see if the problem persists. I was not able to replicate this issue in Windows or Ubuntu. Go to openshot.org/download/#daily and get the latest daily available.

Unfortunately , didn't found 3.0.0-dev build, that's why tested it on OpenShot-v3.0.0-x86_64.AppImage. The problem still persists. In the video you may see that the first time I tried with the Internet connection available and everything was fine, but the second try was without the Internet - and the app froze

Hello @dv0vd I really don't know why this is happening. I am going to ping the lead developer and have him debug this issue.

By the way, you should be able to find the latest DEV Daily build at openshot.org/download/#daily.

[dv0vd]

Well, maybe I'm stupid but I really don't see v3.0.0-dev-daily here https://github.com/OpenShot/openshot-qt/releases/tag/daily, sorry( There are only v3.0.0-release-candidate and v3.0.0-daily, and only v2.6.1-dev-daily.
Anyway, thank you very much for the support, hope you can figure out the problem. Have a nice day!

Hello @dv0vd, please try this to get the latest DEV daily.

1. go to openshot.org.
2. from the top menu options click on DOWNLOAD (https://www.openshot.org/download/).
3. In the middle of the page find and click on "Daily Builds".
4. You should see a listing of daily builds.
5. Please download build #10996

Hello @dv0vd Have you had a chance to try downloading build #10996 and giving it a try?

[dv0vd]

Hi @Colorjet3 ! Yep, just finished testing. Unfortunately, the same exception(((

[Colorjet3]

Thank you @dv0vd for the update. Pinging the development team again.

[dv0vd]

Okay, thanks)

[Colorjet3]

Hello @dv0vd I see that there was no response to this. v3.1.1 has been released so if you don't mind giving it a try and let us know if the issue still exists.

[dv0vd]

Sure, with pleasure!

[dv0vd]

Unfortunately, the issue still exists. When the Internet enabled, but not active it takes more time for the app to start and finally it freezes. However, if I disable the Internet connection everything is fine

Hello @dv0vd Thank you so much for this video. I will ping the lead developer to see if he can take a look at this. He is working on a similar issue reported by another user and hopefully that fix will fix this issue also: #4824

[dv0vd]

Hello @Colorjet3! I see, this is great news, glad to hear that, thank you!)))

Wild guess: could this be caused by #4735?
