Possible database connection bug

[dadamsncsa]

Describe the bug

User received error:

sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError) (2003, "Can't connect to MySQL server on 'gresq.cpzcptl8tfmt.us-east-1.rds.amazonaws.com' (timed out)") (Background on this error at: http://sqlalche.me/e/e3q8)

Tool then refused to launch. for 1/20/2021

Hard to tell if this is an intermittent database connection issue, or some problem with read-only connections.

May need to check logs on database console...

To Reproduce

Difficult to reproduce, user is now able to launch the tool.

Expected behavior

tool launch without error

Screenshots

Additional context

The user almost certainly a read-only user.

this could be a result of the RDS instance size which is "micro" Googling around indicated that this is likely to support at most 40 connections at once. Not sure how many we had during the workshop, but...
