SMS working from one SMSC but not from other provider

Our server was working fine with our domestic carrier for Nepal using Generic SMSC and Twilio for the rest of the world.
2 days ago, Generic SMSC seems to be working but Twilio broke down bringing our service to a halt since OTP was not going out.
We have now gotten test accounts with Infobip and Clicksend (generic) and both of these providers do not seem to be working.
Need URGENT help please.
