I had an API on a server where it works perfectly.
When I migrated it to the new server, it stopped working, I see continuously the
error: net::ERR_SPDY_PROTOCOL_ERROR in chrome and
Solicitud de origen cruzado bloqueada: La misma política de origen no permite la lectura de recursos remotos en https://xxx. (Razón: Solicitud CORS sin éxito) .
If I press the access button repeatedly, it does, but it does not make sense what is happening.
I have two hypotheses:
Regarding the first, I will investigate how to force the server to respond in HTTP, to see if so, at least, solve the error, while investigating the why of it.
Data: Only fails with requests
POST , in
GET does not happen.
