[Rtk-users] Cannot download ExternalData during build (RTK 2.0)

[Maik Stille]

Hej there,


I am getting this strange (MD5 related?!) error during the build process and unfortunately, I don't have any idea how to approach it. It seems like I am not able to download the external data. Maybe the hashtag is not correct?! Did anyone encounter this problem before?


Thank you very much for your help in advance.
