We have an app that pulls data from a custom connector. The app is being used offshore on an oil rig where the internet is extremely slow. This slow internet means its typically takes ~5minutes to pull data. Is there a way to set the time out limit of powerapps to greater than 180 seconds?
To give come context it takes several minutes to open office.com offshore.
This is not a direct answer to your question, and I am sure you have thought about it already, but can you do any of the following?
Do you want to extend the time out limit (more than 180 seconds) within PowerApps?
Currently, there is a limit in Request Time Out within PowerApps, the maximum value of Time Out is 180 seconds (3 minutes). Please check the following article for more details:
If you want to extend the time out limit (more than 180 seconds) within PowerApps, I afraid that there is no way to achieve your needs in PowerApps currently.
I also agree with @Meneghino's thought almost. You could consider to pull data from your data source in batches and cache the data into your local device, e.g. pull 500 records (based on your condition) one time, then save it into your local device (e.g. Mobile device). Next time, you should pull the next 500 records, then save it into your local device, and so on.
