peerjs: unavailable-id after internet connection lost

Hey, this is how i reproduce this error:

if i close and re-open internet connection, it throws this error.

PeerJS:  WARNING You received a malformed message from undefined of type HTTP-ERROR peer.js:1117
PeerJS:  Socket open peer.js:1117
PeerJS:  ERROR Aborting. Error: ID `1` is taken peer.js:1117

and i dont use random ids generated from peerserver. a client’s peer id is always same and unique (i am getting it from user’s primary key value from database)

It is ok while i am switchinh between my web sites pages. (i put peer initialization code in my base.js which loads in every page) ,

swtiching between pages is a kind of disconnection from server right? but why does this happen only when internet connection lost?

i handle this error under peer.on('error'), although i write peer.destroy() here, i doesn’t work.
