Hi @Jomar Vedad ,
Are other users with permissions facing the same problem?
I found a similar thread for you: https://www.reddit.com/r/MicrosoftTeams/comments/hkfqfk/can_someone_please_guide_me_on_how_to_fix_issues/

Maybe you can try to add OneNote as a tab instead. OneNote offers more features and can be used outside Teams.

Hi @Xyza Xue_MSFT ,

Good Day!

I want to inform you that the other users faced the same problem.

Also, I already tried what's on the thread and it doesn't work. It only happens on that specific channel but in the other channel's tab, it works just fine.

@Jomar Vedad What content of the tab did you add? A SharePoint site or Word/Excel file or other?

It only happens on that specific channel but in the other channel's tab, it works just fine.

Do you mean adding the same content into another channel, it could work well?

Please verify the followings:

If you can open the source link of the tab on browser directly.
If your account and other problematic users have At Least Read permission on the source of the tab.
Have you tried to recreate the tab? If not, please try and let's know the result.

If I misunderstand your meaning, please feel free to reply.

update on 12.23--------
Please check if there are any access control policies which may block the access. You can check that as the article.

Besides, there is an official article about Guest experience in Teams, please check if it helps you.

Hi @Wendy Li_MSFT ,

What content of the tab did you add? A SharePoint site or Word/Excel file or other?

what do you mean by what content of the tab did you add? Did you mean what the tab contains? It's just a Wiki tab.

Do you mean adding the same content into another channel, it could work well.

with this, I mean that the wiki tab in the other private channel is properly working but not the same content.

If you can open the source link of the tab on browser directly.

with this, we want to inform you that we are using a guest account, with regards to the question, the screenshot that I attached is already viewed in the browser. Also, I tried copying the link, but the same concern and error occurs.

If your account and other problematic users have At Least Read permission on the source of the tab.

yes, we already checked the permission of the users. only guest accounts can't see the content of the tab, but when the account is with license, it can see the content of the specific tab.

Have you tried to recreate the tab? If not, please try and let's know the result.

we already tried to recreating the wiki tab, but it can be viewed by the guest accounts.

Hi @Xyza Xue_MSFT ,

Apologies for the late response. Here's to verify your questions

If you can open the source link of the tab on browser directly.

We can't open the source link even though in the browser.

If your account and other problematic users have At Least Read permission on the source of the tab.

Yes. Also even though the Owner of the Channel can't access the source tab.

Have you tried to recreate the tab? If not, please try and let's know the result.

It is working when a new tab was created.
