There could be many things which can cause this issue like:
1. There could be there processes which are taking the processor's time. So you need to make sure that other processes are not taking time when running the Sql server. Try to restart the server and check again. It should be working fine.
2. Yo u need to check the server memory because for each transaction, the SQL server try to allocate the memory and if there is no enough memory, the time will lapse and will throw the error message.
3. If there is scenario where the transaction is happening in timely manner in that case also when the re is low bandwidth, this error can cause.
Hope it will be helpful to you.
