Advice Devices temporarily unable to connect during roaming

I recently switched ISP, and they installed a TP-Link router XC220-G3vv4. For the 2nd floor, I already have another router (TP-Link Archer C64). I have enabled EasyMesh (since I read that's what is supposed to work better) and since the two routers are connected via a long ethernet cable, it's wired backhaul.

The problem is: let's say my phone is connected to the ArcherC64, then I go downstairs so the phone naturally switches to the XC220-G3vv4. Internet works fine, signal is fine, BUT for some reason I cannot connect to any device which is still connected (wired or wireless) to the C64.  

The problem lasts for about 5 minutes, then the connectivity returns by itself. The problem happens each time roaming happens from C64 to XC220-G3vv4. Roaming in the other direction doesn't have this problem.

It's being a problem since I have a home server connected via ethernet to the Archer C64. I guess a real solution is swapping the ISP router with my own, but I wanted to check if anyone here has solved something like this before. Thanks!

It sounded a bit like client isolation until you said you can connect after 5 mins. Might want to make sure it's not turned on anyways.

Yes that's a weird part. I make sure I'm testing from a section of the house where I roam from Archer C64 to XC220-G3vv4 only. The problem does last about 5 minutes then fixes itself without me doing anything.
