The http requests are always successful in a WIFI network, but some times failed when use 4G network. After change the APN protocol from IPv4/IPv6 to IPv4, then everything works well.
Access Point Names
The host in some requests might be resolved to a IPv6 address which is not processed by the 4G network due to lack of vendor resource in China. Is it possible that the
http.request API can handle this issue automatically?
