Null response body on login POST

[Misterblue]

I've run into an odd problem where I receive an empty response body for the a login POST. It's odd in that I can log into some grids (Standalone and Wolf Territories) but not others (OSGrid, SL).

I'm running on Ubuntu 24.04 with several of the dotnet SDKs installed.

I"ve so far traced it down to the GridClient.HttpCapClient.PostAsync() call which returns a null for the data. I'm suspecting version mismatch since LibreMetaverse is built on Ubuntu 22.04 and specifies specific versions of some the System packages (probably needed for netstandard2.0). That call to PostAsync causes the XML processing DLLs to be loaded.

I"m still digging, but has anyone seen this type of problem before?

I've verified this problem by compiling the LibreMetaverse sources with my application (so everything is using the same libraries). After compiling everything together, I always receive a non-empty response when trying to log into any grid.
It seems that there can be some library problems when pulling the LibreMetaverse NuGet file into Dotnet 9 or Ubuntu 24.04 systems. Don't know who's the culprit.
