FAQ • Why does the site not open or the API connection stopped working

If problems are detected with sending messages on the primary connection (smsc.ru or smpp.smsc.ru ) the following backup addresses must be used.

For SMPP connections:
smpp2.smsc.ru
smpp3.smsc.ru
smpp4.smsc.ru
smpp5.smsc.ru

For your personal account and HTTP / HTTPS connections:
www2.smsc.ru
www3.smsc.ru
www4.smsc.ru
www5.smsc.ru

As a rule, such difficulties occur very rarely, if there are problems on the line between Internet service providers or if there is a problem situation in the data center (internet, technical work, accident, etc..).
