Access denied to appregnew.aspx (SharePoint online)

[Alex Zakhodin]

Hi,

On my client's tenant I'm using a global admin account (E5 license). When I'm trying to access https://tenant-admin.sharepoint.com/_layouts/15/appregnew.aspx page, I get an error "Access Denied". Am I missing some permissions?

I can access https://tenant-admin.sharepoint.com/_layouts/15/appinv.aspx page without any issues,

I appreciate any help.

Hi Paul,
Thank you for your reply. It helped me figure out my issue. When I first try to use second url (https://tenantname.sharepoint.com/_layouts/15/AppRegNew.aspx) I got another error message "Sorry, you don't have access to this page"). I made my account secondary owner of the "root" SharePoint site, then I was able to access the https://tenantname.sharepoint.com/_layouts/15/AppRegNew.aspx page, and create app registration.
Thank again for your help!

@Alex Zakhodin Hi Alex, how did you make your account as secondary owner of the root Sharepoint site? On which page/link? I am having the same problem even tough I have the admin rights in general.

@blazenkobabic In case you're still looking for the answer, I added my account in SharePoint Admin Center>Select the site>Permissions>Manage>Add your account here. It should work after that.
