Error occurred during the last Teamwork operation

Hi-ya,
I am working in Teamwork using hotlinks for quite long time. But some time very rarely I am seeing this error on and off, after a while it work fine again. The connection with the server is perfect; I don’t see any other error. What might be the root cause for this error? Please suggest me some ideas to get rid of this error before any damage. Thanks in advance.

Server returns error code!
