We are aware that some users are experiencing issues loading our website when using **Safari on Mac or iOS (iPhone/iPad)**, where the page shows a HTTP 500 error.

This is caused by a recent compatibility issue between Safari’s strict privacy updates and our server protection layer (Anubis). It is causing the browser to randomly reject verification cookies. The issue is being actively tracked by the open-source community here:

> 
> \* The exact OS version
> \* The exact browser version
> \* How you installed the browser
> \* If this browser was built from source does it happen when you use the binary that upstream built?
> \* Can you recreate this without browser extensions installed and/or with the default configuration?
> \* The entire list of every browser extension installed
> \* The exact URL of the target server
> \* The exact Anubis version of the target server
> \* What DNS server you are using
> \* Is your DNS server a DNS over HTTPS server?
> \* Did you follow a "privacy browsing" guide when setting up your browser?

**How to work around it for now:**

If you run into this, the quickest workarounds are:

- _ **Try again:** _ Simply try again, either by clicking “Back” in your browser, or accessing the original URL again. In our tests, a second attempt always works.
- _ **Include “https://” in the URL you type** _. In our tests, the error is never triggered when accessing the website via https from the start.
- _ **Switch browsers:** _ Use Chrome, Firefox, or Brave on your device, which seem to be unaffected.

**Note:** The CLARIN Discovery Service (discovery.clarin.eu) is no longer affected, as for the time being we have removed Anubis from its request pipeline.

We sincerely apologize for the friction this is causing and are keeping a close eye on a permanent upstream fix ahead of our upcoming annual conference.
