TimeoutError: [WinError 10060] A connection attempt failed : Except block doesn't execute either

Question

In my program i have a try and except block like so

try:
    if exitCritera(ceLiveprc,peLiveprc,ceEntry,peEntry):
        closeAllOpenAndPendingTrades(cTok,pTok,ceEntry,peEntry)
except(TimeoutError) as e:
    print("Timeout error occured re-trying...:{}".format(datetime.now()))
    time.sleep(1)
    if exitCritera(ceLiveprc,peLiveprc,ceEntry,peEntry):
        closeAllOpenAndPendingTrades(cTok,pTok,ceEntry,peEntry)

the exitCriteria function checks for some data and then calls closeAllOpenAndPendingTrades() and in closeAllOpenAndPendingTrades() there is a contact to the server.

I noticed that i was hitting.

    sock.connect(sa)
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

So i added the except block. But the except block doesn't execute at all. Is there anything i can do to retry once a timeout error is hit?

Answer 1

[WinError 10060] is a Windows Socket Error. Try catching it as an OSError, that worked for me in a very similar case.

Change your code to the following:

try:
    if exitCritera(ceLiveprc,peLiveprc,ceEntry,peEntry):
        closeAllOpenAndPendingTrades(cTok,pTok,ceEntry,peEntry)
except OSError as e:
    print(e)
    print("Timeout error occured re-trying...:{}".format(datetime.now()))
    time.sleep(1)
    if exitCritera(ceLiveprc,peLiveprc,ceEntry,peEntry):
        closeAllOpenAndPendingTrades(cTok,pTok,ceEntry,peEntry)
