Safari 15 not opening websites - "a problem repeatedly occurred"

The automatic update to Safari 15 (Catalina) came across yesterday and now a huge number of websites no longer open. The problem seems to begin after attempting to login - the redirect confuses the browser. Does anyone know what's going on?


Switching to Opera and Brave until this gets fixed. See screenshot for typical error page below.....

To Wheel64:

This is an update to my original post and referencing your problems. Like you I suspected it was not just Safari 15. So.....

I reinstalled my Hard Drive -using the Restore feature - from my Time Machine Back-up of a few days before, i.e. before downloading the Security Patch and Safari 15.0 at the same time on Sept 21. which then caused all these problems.

The re-install took about 3 hrs. but it sorted everything out, and no issues. NOW the good part...

I decided to move step by step to update, to be current.

So I only allowed Apple to download and install the Security Patch, on its own. Once installed I checked everything was OK. And everything worked OK as before, but I am still using Safari 14.1.2

So, then and only then I downloaded and installed, ( as separate instruction) Safari 15.0 and nothing else. This item just took less than 5 mins. and my system didn't need to re-boot.

Again I tested everything and everything worked... no issues.... all websites opening their log-in pages.

My only thought is that installing the Security Patch and Safari 15.0 simultaneously caused the bug on my MacBook pro to prevent accessing -in my case - a whole host of financial institution log-in pages. However by downloading these 2 items separately allowed my system to update with no errors or issues.

Thanks LD - Of course I know how to post a screenshot - I posted one before and for some reason it's now gone!

See the little question mark box? Gone!

Trying again...(screenshot below) FWIW there are reports of this all over the internet today. It's not just me. All kinds of bugginess with Safari 15.0 in addition to this problem!

thanks for the Screen shot.


Yes I realize it is a re-occurring issue for some...I am trying to drill down on this issue.

You can try and clear cookies for that particular website and try again.

I have had the same problem ( but only for Financial Institutions websites, including insurance co.s - one outlier -Xfinity and AT&T) Originally like you I thought it was Safari 15.0 which I downloaded on 9/21/21. So I reinstalled Safari 14.1.2 from Time Machine Back-up and the same problem continued.

It's not Safari...it's the Security Update to MacOS Catalina 10.15.7 which I believe is causing the problem.

So I re-installed ( Restored) my previous MacOS operating system /Hard Drive ( not just HD Mackintosh - Data) but everything as at 9/19/21 - i.e previous to the updates. And now everything for me at least works perfectly. No issues

Someone else suggested upgrading to Big Sur but I was not that keen, so effectively I have down graded to 10.15.7 before the Security Update/Safari 15

To Repeat, I don't believe the bug is in Safari.... it's in the Security Update posted at the same time.

But am no expert on this. All I know is that by reinstalling a previous version of MacOS from my Time Machine Back up I solved my problem

I believe this is more than a Safari 15.0 issue. I also updated safari when the latest security patch came out, Sept 28?

I have posted in the user community. at first I couldn't login at all. reinstalling the Safari 15.0 didn't really help. after all, it contains the same bugs. I have not seen an update yet. I can login to my bank, BUT I CANNOT GET A TEXT FOR 2 FACTOR AUTHENICATION !! I have to either get a phone call or an email. I think this is a bug in the security patch ???


I have the same problem if I try to login to my bank, using the CHROME browser, which is why I think it's a security patch bug !!


I seem to be able to browse and use most other web sites, with either browser. I have not seen anything helpful in the user community , as it needs a patch from Apple. I hope apple is monitoring theses discussions.


I will try to connect with apple support just to get my problem registered with the people responsible for fixing it.


Good luck to everyone.
