Model converter website freezes while converting

Hello! Guys, the conversion freezes by 2%. The same files (OBJ+MTL) were normally converted 2 days ago. Sorry for my English.
modelconverter dot com

Thanks.

Not sure who runs model converter dot com, perhaps it is worth trying one of the converters listed on the Khronos website: https://www.khronos.org/gltf/ ?
