Dear Hanif,
Good day!!
I would like to confirm whether the link shared with other users is the Anyone link and if it's expiring in around 30 days. If yes, I would like to let you know that you need to change the settings in the SharePoint Online Admin Center, please follow the below steps:
Open the Office 365 Admin Center> Click All Admin Centers and click on SharePoint Online Admin Center> Sharing> At "Choose expiration and permission options for Anyone links", either uncheck or increase the number of days for "These links must expire within this many days".
If this doesn't resolve the problem, please don't worry, we can work together and resolve the problem, so please let us know whether this behavior happens only to specific users or all users.
Thanks for your patience and understanding.
Best Regards,
Sophia
