Running LS 3.22 (also did the same thing with LS4) on an IIS 10 box with PHP 7.2.7 (also happened with PHP 7.4) and MYSQL 8.0.21. When a participant is using Chrome and we try to redirect outside of our domain, they have to hit the submit button twice and then they get the "session has expired" error. Only happens (at least that we can replicate) with Chrome.

I'm not sure if it is a LS issue or something on our network side - since it's only an issue with Chrome.

Any ideas would be greatly appreciated.

I recommend to open a bugticket. If you can reproduce the issue with Chrome, the used version of Chrome should be mentioned.

Jelo,
Thank you. I have submitted a bugticket. I wasn't sure if there was just some setting I was missing or if anyone else has had a similar issue. The issue is also present in Safari (most recent versions of it and Chrome). Not an issue with Firefox and Edge (current versions of each). I am able to use an end_URL that is in the domain to an HTML redirect to the out of domain site (a workaround).
