Is it possible the serve docspace from subpage ?
Hi @dsl400 
I believe it should be possible to serve DocSpace from a subpage like my-site.com/docspace.
While I haven’t personally tested this setup, there are no specific instructions for DocSpace, unfortunately.
You will most likely need to configure proxying on your reverse proxy server.
I recommend taking a look at the following examples that deal with proxying for ONLYOFFICE Docs. These should give you a good starting point:
Hi @Nikolas, after a few attempts I figured out that it can not be done without modifications to the source code of the client app
There are many places in the client web app that need to be modified for this to be possible
Hi @dsl400 
Thank you for your feedback. Currently, there are no official instructions for serving DocSpace from a subpage without modifications to the client app’s source code. However, we are gathering requests like yours, and if there is sufficient demand, we will consider implementing it.
It would be very helpful if you could provide more details about the specific use case you are trying to achieve. This way, we can compile a list of users and their cases for future reference.
Thank you!
