I have a dataflow setup for a long time which refresh UK morning time. Over the last few days, the refresh is failing with strange timeout error. Yesterday, the refresh failed after 30mins, with the error below. The dataset on which the I got the error was only executing for 1min and 30.9secs.

I manually started the refresh and it completed successfully.
Today again the refresh failed with the following error after 44mins. This time on a different dataset which was executing for 1mins and 30.6secs.

If your dataflow is in the premium workspace, see this known issue document:
Known issue - Long running, failed or stuck dataflow in Premium Gen2
As a last resort, you can try swapping the workspace out of Premium to Pro and wait a few minutes. Then switch the workspace back to Premium. This solution may help to provide relief, but the issue could reoccur.
