Your issue seems to be browser related, try cleaning the cache and submiting again, else try a different browser. Also keep in mind that there’s a timeout between the steps - so if you leave the tabs open for too long you might get these types of errors.
Hey there! The same problem happens to me when I am trying to work with the PRODIGY-LIGAND. It is showing “Internal Server Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.”. In the same browser, HADDOCK 2.4 seems to work fine.
Thanks for reporting this, I’ve identified the issue and it could be related to the parsing of ensembles of ligands; To bypass this you can split the ensembles and do multiple submissions (if that’s doable).
We are working on a patch and will let you know once its fixed, sorry for the inconvenience.
I’ve applied several fixes, please try cleaning your cache and re-submitting, if for some reason that does not work, try a different browser - if still you find any issue, please let us know.
