It works the other way round, you should provide what you have, instructions on how to export your current configuration, anonymize sensitive data and posting on the forum here:

then the more expert members may be able to spot where the problem is and provide targeted suggestions/corrections.
Particularly with VLAN’s sometimes a teeny-tiny mistake in configuration can make everything fail to work and guessing what specific settings you are using would be a futile hit and miss game.
Providing also a (simple, even the photo of a sketch drawn on paper would do) network diagram would be useful to understand your situation.
