Hi Ilia, 53 is a xrootd 'related' error, which includes checksum error, here's the full list: ``` const uint16_t errNoMoreFreeSIDs = 301; const uint16_t errInvalidRedirectURL = 302; const uint16_t errInvalidResponse = 303; const uint16_t errNotFound = 304; const uint16_t errCheckSumError = 305; const uint16_t errRedirectLimit = 306; ``` Why do you claim the error code is wrong?
