Hi,
About 5 days ago users of our App have started receiving a certificate error:
"The certificate for this server is invalid. You might be connecting to a server that is pretending to be “skyapi.onedrive.onedrive.live.com” which could put your confidential information at risk."
Obviously, the URL looks incorrect (too many "onedrive."'s in there...). The trouble is this URL is generated by "accountchooser.js" in code that looks like this:
e.skyApiBaseUrl = "https://skyapi.onedrive." + document.domain + "/API/2/";
We use the OneDriveSDK via a Cocoapod (nothing has changed here in years) and our App hasn't changed anything here in a similar time frame. So something recent looks to have changed, either in the accountchooser.js code, or in how "document.domain" is calculated/determined on iOS. For reference, our users are seeing this on iOS 15.3.x and iOS 15.4, so latest stable production releases.
Is anyone seeing anything similar? Any help with where or how we should raise this issue would be helpful...

@Mark Mc , You are correct . Ideally the request should go to “skyapi.onedrive.live.com/API/ ... ". As the error is not from Azure AD , I have updated the onedrive tags so that right set of experts get notified for this issue.
Hi @Mark Mc
Welcome to Q&A forum ~
But as "office-onedrive-client-itpro" focuses more on general issue of OneDrive, such as deployment, installation, and troubleshooting like file synchronization.
To help you better on this issue, I would suggest you post new threads on forums that the following link mentions.
OneDrive developer community
Thanks for your understanding.
Hi Emily,
I appreciate your response, however I'm afraid it's rather unhelpful.
That's just a link to the generic help section. Unfortunately this seems like a run around. I've been sent here by Azure Support, then told I don't have the right tags, then told to try again at the generic help page. It's quite Kafkaesque.
There's an issue here affecting hundreds of OneDrive users, and more by the day. We're a few days in and no one seems to know or be able to help with even where this should be raised? Is there anyone from Microsoft that can actually route or triage this to the right people?
Super frustrating, but thanks for the response at least.

This certainly has been happening to me for at least 5 days. It’s pretty annoying.

Also facing the same issue and looking for a quick resolution.
We managed to solve this issue for Strongbox users over the weekend. Please update to 1.55.2 for a fix.
NB: You may need to re-add your OneDrive databases ( + > Add Existing > OneDrive) to see the effect.

We are investigating this issue and will let you know when we have a path forward. We apologize for the inconvenience.
Long term if possible, it would be best to start exploring if you can switch your app to using the Microsoft Graph SDK instead of the OneDrive direct SDK. The Microsoft Graph SDK for Objective C can be found here: https://github.com/microsoftgraph/msgraph-sdk-objc. The patterns should be similar between the two libraries but the Microsoft Graph SDK is newer and uses more modern platform components from IOS.
That won't necessarily fix your problem today and I'll try to provide an update as soon as we have one for the current issue.

Hi @Mark Mc
Could you please advise how to solve this problem? I came across same problrm in my app.

Seeing the same error for the last few days while IOS Stronbox App tries to log in to access a data file on 365 OneDrive.

The Strongbox app developer made an update on 3/6/2022 that fixes its interface to OneDrive.
Hi,
We're still verifying this fix for users, but for anyone here who would like to try our new MSAL integration:
Update to this version (1.55.2)
NB: You will probably need to search for 'Strongbox' on the App Store, and click/tap in to it, to see the "Update" button as Apple slowly roll it out.
Once you've got the latest version installed, you will need to migrate your existing databases over to the new integration (called "MSAL"). To do this simply go to:
Preferences (Gear icon) > Advanced > Migrate OneDrives to MSAL
Alternatively you can simply add your database again by:
Could you let us know how it goes? We've confirmed the fix on our side, but we still need to make sure our users can migrate successfully. Thank you.

Keepass Touch app on my iPhone is throwing the same error when attempting to sync with OneDrive. Any ETA on a fix?
I too have this issue in KeePass Touch
