Hi @Abhisek_Dey
Server access
I am able to load up the website today. Are you able to at least log in?
We had a report back on October from another user. They were having some issues at the server.
- Our topic at this forum → Is W4M under maintenance?
Where I was checking at the dedicated community forum the server hosts for discussions
I don’t see any topics about the batch correction step having a technical issue in their workflows (or, I missed it) but I do see people asking about other tool errors and getting direct help. This is one example. The community is waiting for more information about the error to help.
Note about the forum's default language
The forum hosts discussions in French by default but that can be adjusted for anyone who has an account there. I don’t speak French well enough to read/write myself, and I wanted to test using a browser level translation, so I just tried this using Google Chrome and turned on automatic translation from French to English. It works great! It allows the entire site to be navigated even without an account all in your own language. You can write back in English and the community will be able to read your messages with the Discourse translation settings, or with using the browser-level translations (how I did it or with another browser’s language options).
How to get help with your current error on the W4M server
-
Share your history with error here and we can try to help with the usage. Using Galaxy is about the same no matter which server you are working at. Then, if it needs more, we can help you to report this to the administrators at their forum with the context we create here from the review.
-
Share your error with the error directly at the W4M site. You can get usage help the same as here but also two more things: help with making scientific or logical decisions when using their workflow (since these are the authors) and help with any issues that might be at a lower level on the server (the administrators who run the server).
We hope this helps to explain! It can be difficult to diagnose tool errors without seeing all of the details. I’ll watch for your reply. If you decide to create a topic at the other forum, you are welcome to link it back here to let us know! Thanks! 
Sharing an error for feedback
If you are not sure how to generate a history share link to the history that contains the workflow output with the error, please see this guide. There is a toggle in the application, then you copy the link and paste it back into your messages.
