Hm, while I wasn't able to reproduce the error, even while running Text Plates and several planet mods, I've attempted a fix; try v1.0.14 and see if you can place the hub chest.
I've added some logic that prevents the customized versions of the textplates from reserving filtered slots in the Hub Chest (honestly, not sure why it wasn't done this way to begin with, still working with a lot of carryover code from the original mod author). The non-customized version (base concrete that allows you to select a letter) is still allowed in the hub chests.
In addition, any item that was marked as "hidden in Factoripedia" is also banned from the hub chests. This mostly includes vehicle weapons (which are technically registered as items), and some debug items, hopefully shouldn't prevent any actual items from being transported, but no guarantees. On top of that, I've manually banned most of the planners and remotes I could find, including blueprint, decon, upgrade, discharge, artillery, and several mod-added planners and remotes that couldn't be blanket-banned by item type (a lot of them are capsule type, same as grenades and combat bots)
With that being said, it appears the vast majority of remaining items from my testing are rows upon rows of barrelled fluid items, which could in theory cause the overflow error by themselves. From my testing, it was still only about the halfway point of the current capacity limit (not sure if I can raise it, since it's already set to a very high number, which was originally to accommodate text plates)
