Sanborn Maps

Hi,

We just had a patron alert us that they can no longer view Sanborn's
full-size map image when they are outside the library. It sounds like they
do this fairly often so I believe this is a new problem.  What's a little
odd is the first time I tested outside our network (on my home computer) I
was able to view the larger image ok (even though I'd never used that
database before).  However, it didn't work on my phone and when I tried
again about an hour later, it no longer worked on my home computer either.
My best guess is that's a red herring, but I'm not sure.  In any case, I
can no longer see the larger image on any computer I try outside the
library network.

To replicate the error:
1) Via EZproxy, I access the Sanborn maps here:
https://ezproxy.spl.org/login?url=http://sanborn.umi.com
2) Login to EZproxy with my patron username and password.
3) Click Browse and Explore and choose the various option until I can see a
map thumbnail.
4) When I click on the thumbnail to get the larger image, the page reloads
and says "Unable to open [object.Object]: Unable to load TileSource"  My
Chrome console says "No TileSource was able to open
/data/maps/al/reel01/0001/0001.xml #document" (titlesource.js:692)

We're on EZproxy 6.1.16

Proquest suggested we try the newest OCLC stanza (
https://help.oclc.org/Library_Management/EZproxy/Database_stanzas/ProQuest)
instead. Though I see a note saying this is suppose to be compatible with
6.2.2 and above.

My next step is probably to upgrade EZproxy but I'd really rather not do
that this month if I can possibly avoid it.  Any other suggestions of
things we can try?

Thanks!
