third party add-ons don’t show up i get error message" could not retrieve directory information this could be due to the network not being connected." but it is connected i added other addons from repo. and i have watched tv on it so it is working, and i have turned on addons from unknown sources. any suggestions?

If you have no problem accessing other repos, such as the official Kodi repo, then your problem is with the third party repo, not Kodi or OSMC.

i have tried a few others and get the same error?

What repos? What error does the Kodi log report? You are providing almost no info to go on here…
