I have the same situation

Same. There was a problem with the hosting, but it seemed to work. But crons don't work now:

I recommend transferring servers to Hetzner. Cheaper and more stable.
Choose a data center that is geographically closer to your key customers to minimize response time. If you have, for example, an online store with which integration is required, then place the servers in the same data center to use the internal network for the transfer of synchronization data.
It can be transferred in 1-2 hours of work, depending on the amount of data.
After the transfer, you will only need to change the settings in the services that are tied to the IR, such as Binotel or Openkart.
