Hello,
We are reaching out as a company providing Wi-Fi connectivity services through captive portals to report a potential issue identified after upgrading to iOS 26.
Since the release of this version, we have received multiple reports from customers who are unable to complete the authentication process on captive portal networks. The observed behavior is as follows:
The device correctly detects the Wi-Fi network. The connection is established at the link level, but after entering access credentials and proceeding to the next login step, an “error opening page” message is consistently displayed. When the user taps “OK,” the captive portal mini-browser closes. As a result, the user is unable to authenticate or gain internet access.
We have verified that:
Our network infrastructure and captive portals function correctly on other operating systems (Android, Windows, and previous iOS versions). No recent changes have been made to our platforms that could explain this behavior. The issue appears to be consistently reproducible on devices running iOS 26.
Additionally, we have identified similar reports from users in public communities like reddit, suggesting this is not an isolated case.

Given the direct impact on user experience and services relying on web-based authentication, we would appreciate any information on whether this behavior is being investigated or if there are any technical recommendations to mitigate the issue.
Thank you for your attention.
