Title

"connection timed out" error, r(2)

Description

If you see

connection timed out
r(2);

then an Internet connection has timed out. This can happen when

a. the connection between you and the host is slow, or

b. the connection between you and the host disappeared and so
eventually "timed out".

For (b), wait a while (say 5 minutes) and try again (sometimes pieces of
the Internet can break for up to a day, but that is rare). For (a), you
can reset the limits for what constitutes "timed out". There are two
numbers to set.

timeout1: the time to establish the initial connection

By default, Stata waits 120 seconds (2 minutes) before declaring a
timeout. You can change the limit:

. set timeout1 #seconds

You might try doubling the usual limit and specify 240. #seconds must be
between 1 and 32,000.

timeout2: the time to retrieve data from an open connection

By default, Stata waits 300 seconds (5 minutes) before declaring a
timeout. To change the limit, type

. set timeout2 #seconds

You might try doubling the usual limit and specify 600. #seconds must be
between 1 and 32,000.
