 ## Troubleshooting 
 If you are using a remote server and the program crashes or gives you an error, here are things you can try. 
-
 - try to lower the concurrency number to as low as 1 
 - make sure you didn't hit the API limits of your provider 
 - change the node provider 
 - change the block numbers 
 - go with a smaller block distance (between start and end)
+- make sure output directory exists in same directory as binary
 - better solution : run you own node and connect to IPC using ``` /root/.ethereum/geth.ipc as -u  (url) ```
