nie jestem w stanie zinterpretować tego traceback. Czy ktoś z pewnym doświadczeniem w flask-socket.io może pomóc?
Nie zamieszczam żadnego kodu, ponieważ nie wiedziałbym od czego zacząć. Wszystkie pliki w systemie traceback pochodzą z zainstalowanych modułów.

Jak wykonać swój serwer? Czy jest to aplikacja WSGI skonfigurowana dla serwera proxy Nginx, czy po prostu opcja debugowania z wiersza poleceń? Pytam o to, ponieważ mam przeczucie, że serwer jest wykonany w taki sposób, że nie jest w stanie obsłużyć wielu żądań. –
