Intermittent AppSheet sync errors

Hei all!

Today (19.06.2025) and yesterday, our AppSheet app started experiencing sync errors - based on the AppSheet Performance Analyzer, some API calls take 20 seconds and then fail. And then the next ones complete in 0.5-2 seconds successfully. 

 

Our AppSheet app is backed by a SQL server running in Google Cloud, but I do not see any issues there - the CPU, memory, and read/write look within optimal limits.

Is anyone else experiencing Intermittent sync errors these past days?

Hi,
We also have some application that is backed by SQL Server from Azure, and we experience intermittent connection to the SQL Server for the past few days also.
This is our Error message 
"Error: Data table is not accessible due to: A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 35 - An internal exception was caught)."

Admins please help.

Status update

It seems to be better today, no failures yet.

@Jana_Mandic , @Mike_Procopio 

From last week to this week, the app has been intermittently slow. Synchronization delays are obvious. Also, adding and updating data can take a surprisingly long time.

We have received information that this phenomenon does not occur all day, but at certain times of the day. It seems that the operation becomes particularly slow around 5:00 PM Japan time. In UTC, it is around 8:00 AM.

The frequent server downs that occurred until last month have disappeared, but the delays in synchronization and data processing are just as serious as the server downs. This defect is causing automations that are not executed, which is disrupting business operations.

Same in South Africa, all my client PDF automation bots are timing out, they spiked from 45 seconds successful to all 120 second timeouts consistently.
