Hi all, we are setting up a new APN for MMS. This APN has a different name and addressing to the current one. Connections from new APN are rejected by MMSC server with following error: HTTP1.1/503 Service Unavailable The reason is Connection not allowed for IP address X.X.X.X We have checked configuration out an we do not see any parameter defining a whitelist of IPs. We are wondering if the fact of using a new APN name could be the reason. Any help is welcomed. Thanks in advance. Kind Regards, Antonio. | |||

Hi Antonio, Check the IP address restrictions here for the MMSC: http://www.nowsms.com/doc/system-settings/configuring-the-web-interface-and-smpp-server The error could also be coming from the WAP gateway, which has similar settings on the "Options" or "Misc" page of its configuration settings (location varies by version). -- Des NowSMS Support | |||

Hi, the problem was due to WAP gateway. We have updated the configuration and it works now. Thanks for your support. |
