ERROR:kiteconnect.ticker:Connection error: 1006 - connection was closed uncleanly (None)

I am getting below errors while placing orders :
ERROR:kiteconnect.ticker:Connection error: 1006 - connection was closed uncleanly (None)
ERROR:kiteconnect.ticker:Connection closed: 1006 - connection was closed uncleanly (None)

I could able to get the tick data but while placing the orders I am getting above error since yesterday..
I am not calling any on_close() function..

Earlier connections used to get established automatically.. but now with the same code I am facing above issue.

Please suggest what to do..
