Routing collabora code through NPM to NextCloud (Solved)

This might be outside the support mechanism here, but I've used this outside NPM (with linuxserver swag) and it worked fine... I've routed all my containers through NPM, and they all work fine, except for collabora. With swag, it worked no problem. Nextcloud sees my collabora server and reports that it can reach it, but when I try to open a document (I know the document works, as I created it in collabora with swag)..

I get this error over and over

00001-00034 2023-09-28 08:04:35.381070 +0000 [ websrv_poll ] ERR #24: #24 bad request: [GET /cool/https%3A%2F%2Fnextcloud.mydomain.tld%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F1396_instanceid%3Faccess_token%3DK3Y7Xpq3TmuRtipegaq3T0zVH4h3LBXg%26access_token_ttl%3D0%26permission%3Dedit/ws?WOPISrc=https%3A%2F%2Fnextcloud.mydomain.tld%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F1396_instanceid&compat=/ws HTTP/1.1 ...]: Invalid or unknown request.| wsd/COOLWSD.cpp:4061

I can reach the domain via collabora.mydomain.tld and get the traditional "OK" which confirms the server is working. Nextcloud reports that the server is online and reachable. In the past, this pretty much ment NC Office was working fine.

My compose for collabora is relatively simple...

version: "2.2" services: collabora: image: collabora/code container_name: collabora environment:

aliasgroup1=https://nextcloud.mydomain.xyz
dictionaries=en_US ports:
9980:9980 restart: unless-stopped

Any help or suggestions on this would be greatly appreciated.
