Cannot find or open the PDB file.

Since .Net Core 3.0 I can no more debug with pdb files… I get this:

* Searching for 'System.Private.CoreLib.pdb' on the configured symbol servers..
Loaded '/usr/share/dotnet/shared/Microsoft.NETCore.App/3.0.0/System.Private.CoreLib.dll'. Cannot find or open the PDB file.

Seems that files are not found, as the debugger try to reach some ip that either have bad certificates, or fail to respond… Here some of them:

131.253.33.219:443
185.199.108.154:443
219.197.79.204:443
