I have an isolated problem with just one user who is viewing this installation from a U.S. Military base. I think this has something to do with this error as I'm unable to replicate it, but I thought I'd post it here to see if there's anything to be done about.

I preface this support request with the fact that I know that this site is a) an unsupported Joomla version. b) an old version of Admintools, and c) an old unsupported PHP version. These may also be playing a role here. I'm working on upgrading sites for a number of installs and haven't got to this one yet.

I have never seen this error before.

So when my client tries to access the site from his browser, from inside a U.S. Military base, but otherwise, no other known security issues, instead of the site coming up, he gets this code error:

Fatal error: Uncaught exception 'InvalidArgumentException' with message 'The value "" is not a valid IP address.' in /plugins/system/akgeoip/lib/vendor/maxmind-db/reader/src/MaxMind/Db/Reader.php:98 Stack trace: #0 /plugins/system/akgeoip/lib/vendor/geoip2/geoip2/src/GeoIp2/Database/Reader.php(130): MaxMind\Db\Reader->get('') #1 /plugins/system/akgeoip/lib/vendor/geoip2/geoip2/src/GeoIp2/Database/Reader.php(91): GeoIp2\Database\Reader->modelFor('Country', '') #2 /plugins/system/akgeoip/lib/akgeoip.php(49): GeoIp2\Database\Reader->country('') #3 /plugins/system/akgeoip/lib/akgeoip.php(73): AkeebaGeoipProvider->getCountryRecord('') #4 /plugins/system/admintools/admintools/pro.php(2484): AkeebaGeoipProvider->getCountryCode('') #5 /plugins/system/admintools/admintools/pro.php(143): plgSystemAdmintoolsPro->geoBlocking() #6 [internal function]: plgS in /plugins/system/akgeoip/lib/vendor/maxmind-db/reader/src/MaxMind/Db/Reader.php on line 98

It looks like his browser is not providing accurate IP info, but I don't know why that's breaking the script. It might qualify as a security fault, but I would think Admintools would just block him.

He can access whatismyipaddress.com and it will show a valid IP for him, although the domain of the server suggests it is a proxy server.

I tried disabling the Geo IP plug in and re-enabling it, but neither solved the issue.

Are there any ideas on what's causing this fatal error?

Hello Eric,

in later version of the GeoIP plugin we added the code to handle such edge cases. Exceptions are caught and the user won't suffer any issue.
Looking at the details you provided, first of all you should update your Admin Tools version, take a look at the compatibility page to find the link to the correct version.
You'll have to update the GeoIP plugin, too. There aren't any special requirements, so it should work, just take a backup before updating it (better be safe than sorry).
