Yup, mobile it's fine with the same nostream relay for read and write.
I'm testing other relay software types on desktop and it seems strfry works on desktop, so many it's limited to nostream on desktop (nostream on mobile is good).
Discussion
perhaps its the AUTH event challenge that needs to be exchanged between the clients and relays but it shouldnt br a problem?
nostr:npub19qcnj6qzrhv92pf8tuhd74wcl6c8r2y2mmrp5pknfy3m2lsrd7xs6y7xw2 can we debug with a nostream relay specifically and see how it goes ?
you can check our relay it is based on strfry wss://nostr-01.yakihonne.com or wss://nostr-02.yakihonne.com if it works with strfry it means there is something with the nostream implementation nostr:npub1qqqqqqyz0la2jjl752yv8h7wgs3v098mh9nztd4nr6gynaef6uqqt0n47m can we take a look at this from your end if you have time?
Just tested and it works on desktop with the yakihonne strfry relay (all other relays removed)
The odd thing is the nostream relay works fine for mobile, also all other relays removed. I guess something to do with nostream and desktop specifically?
