Most SES.Hospedajes errors are caused by two things: expired or incorrectly installed digital certificates, and incorrect date or document field formats. Check these first before diving into specific errors.
You see an SSL warning in the browser or the connection fails entirely when accessing the SES.Hospedajes portal.
The system returns HTTP 403 when submitting via web service (API).
Note: This is the most frequent cause — a mismatch between the NIF of the web service credentials and the NIF of the establishment's registration.
The submission is rejected with an error mentioning invalid XML or wrong field format.
| Field | Correct format | Common mistake |
|---|---|---|
| Date of birth | YYYYMMDD | DD/MM/YYYY or DD-MM-YYYY |
| Sex | M / F | Male / Female / 1 / 0 |
| Document type | D (DNI), P (Passport)… | Full word ("DNI", "PASSPORT") |
Gotocheck validates all fields in the correct format before making the submission. Users who use the platform never encounter this type of error.

This usually means the Ministry servers are overloaded at that moment. Wait a few minutes and retry. With Gotocheck, retries happen automatically — you never miss a deadline because of a server error.
