not sure which channel to post but how can ideal with this error "SuiteTalk concurrent request limit exceeded. Request blocked"

You have too many concurrent script requests happening at the same time. You would either need to reduce your scripts OR get the SuiteCloud + license to get more processing lanes.

we have two diffrent apps running

Which apps?

one in house and one outside

You should look at the concurrency monitor. Customization>Performance>concurrency monitor

i look into it
