I can confirm the problem too. all sub links has with 4.x.x versions,. some can't add and some can't connect. also windows software has these problems too. for windows we can downgrade to 2.x.x old version without problem but on IOS we can't. 2.x.x versions had no problem at all with sub links and connecting to same configs on IOS and windows.

The latest iOS version does indeed have a problem; it cannot import subscriptions.

Android version has the problem, too, while Windows version works fine. Plus, I found the old sub link works when I update the app, except for edge browser. I thought it was the sub link, but later I found i can't even important subscription (which works for 2.5.7 version

Issue with Subscription Links – Base64 Error in V2Ray Clients

Hello Hiddify Team,

I hope you are doing well.

We are currently experiencing an issue with subscription links used in Hiddify. When users import the subscription, some V2Ray-based clients return Base64 decoding errors, and the configurations fail to load properly.

Issue details:

Subscription links fail to parse

Base64 decoding error appears in V2Ray clients

Some configs are ignored or imported as empty

This problem started recently and seems related to how the subscription content is encoded or delivered.

Request

Could you please investigate:

Whether the subscription output format has changed

If there are encoding issues in Base64 generation

Any compatibility changes with V2Ray/Xray clients

If there is a recommended format or workaround, we would greatly appreciate your guidance so we can assist our users.

Thank you for your support and for your continued work on Hiddify.

I also have this problem. Subscription can be used in the old version, but not in the new version.
