Nuget restore fails for FluentValidation >=6.4.0-beta1, if additional Package Soureces are defined

[chubbson]

I was trying to use FluentValidation.AspNetCore 6.4.0-beta9 everytime i am trying to restore it from Nuget it results in a timeout error. Seems the same error for all version 6.4.0-beta1 -> 6.4.0-beta9. I wrote a StackOverFlow Question describing my workflow. Is that an known issue? Any workarounds for that?
FluentValidation 6.4.0-beta* nuget package restore failed, operation timed out

Sounds like a nuget problem, not a FluentValidation problem so I don't think I can be of much help. The only thing I would suggest is from looking at the error you reported on stackoverflow, nuget is trying to pull from http://10.0.10.49/NugetServer. That looks like a custom internal nuget feed to me....try switching back to the default MS feed instead.

I'll check that alternative internal Nuget feed next.
As hint, like described in the StackOverflow Question, i also tried to restore
FluentValidation 6.2.1
FluentValidation 6.3.3-Alpha
FluentValidation 6.3.4-Alpha
which worked well to restore from nuget. And restoring other Nuget packages does success as well

Okay, I have deactivated my additional NuGet Package Source from 10.0.10.49, and now i can restore FluentValidation 6.4.0-beta9.
Strange behavior. I'll take that issue in mind for later problems. I'll Close this Question. Thank your for your fast response.
