This appears to be a message from the UserAuth addon.
Looking at the source code, you may be able to allow changes of the IP
address during the same session with such a line in config.php, before
including the userauth2.php file:
$UA2EnforceFixedClientIp = false;
If an IP address changes in the same session, either:
1. you actually changed IP address (may happen often if you use mobile
3G/4G internet, on the move, or if your device disconnects and
reconnects a little later, or you passed through some load-balancing
proxy), or
2. someone else was somehow able to hijack your session ID and is trying
to access the wiki.
In the past IP addresses changed rarely during a session (~ 20 min) so
the addon considers this risky.
If you configure your wiki to redirect all visitors to the HTTPS/SSL
version, the risk of having your session ID stolen is much lower.
By default, PmWiki doesn't restrict a session to a single IP address.

I have recently been getting the following error at random times
accessing pages. Pages are public read only and admin write only.
This has been reported by other users as well. Running version
pmwiki-2.2.107
Session client coupling inconsistent (IP address changed?). Stopping
for security reasons.
