Hello, Alvaro et al! Please pardon the late reply. In our latest exchange, on 6 July 2022 at 09:01 [JST], I received this from Alvaro Cornejo: IP is assigned by the OS system. In your case, AWS.

I assume you will need to ask AWS to assign/configure you a fixed public IP address.

Yes, the IT staff eventually figured out what had to be done was to adjust the AWS settings for this particular website. They just wanted confirmation that it wasn't something else going on, probably in Koha, that was causing the premature logouts. The appropriate settings were changed, and the issue vanished. Thanks for the confirmation. There was also this response from Barry Cannon: To temporarily get around this problem you can disable the

SessionRestrictionByIP system preference in Koha. This binds the user's session ID to their public IP address. If it changes, the session becomes invalid and Koha will prompt for a new login.

The changing IP seems to be unrelated to AWS as they appear to be your ISP addresses. Does the same problem exist outside of your organisation? For example, at home or on a mobile device. If not then the problem is most likely related to an outbound proxy at your end - your IT might look into this. If it still happens elsewhere then perhaps your ISP is doing something with transparent proxying that they might be able to help you with.

This is good to know in case the premature logouts resume in the future. It will be something else to look into. But for the time being, the new AWS setting seems to fix the problem.
