Hi everyone,
I have this situation:
when I work with DataBase Pens there is no problem, but when I work with Tag pens, the CTG seems to get blocked for a while, appearing the error shown in the attached picture.
why is happening this? How can this be solved?
Just a guess, it’s taking to long to return the data.
The default timeout is 60 seconds. I’ve had this behavior when the query takes longer. How much data is in the database?

But it all indicates that is about the amount of data, because I have tried it in my computer with very few data, and works perfectly while, the one from the client suffer from the error I explained in the first post.
Does anyone have another explanation?
Thank you for everything! 
I got around it by partitioning the data so that there was about 20,000,000 rows per table. Changed the timeout to 5 min.Then told the customer not to look at more then two partitions at a time or wait several minutes for the trend to show up.
Wish I could remember where that timeout was again 
If you look on the status page on the gateway, you can see the query and how long it’s taking.
Client read timeout - in the Designer under Configuration > Properties > Client > Timing
