Problematic permalinks

After migrating my local site live and editing some last bits I suddenly started to have permalinks problem. My home page works fine, and also do the some links on the primary menu, however when trying to see pages they do not appear. I am directed to a seemingly correct page (with the correct url) but my page isn’t actually opening. All the pages are existing in my admin panel and I am able to edit them, but if I press preview changes, the faulty page opens again.

I have tried deleting and editing htaccess file and trying to reset permalinks settings, but for no result.

Thank you for your help!
