Hi, since last month i get very often access blocked when getting GPS from address or address from GPS. Sometimes i get result but its very rare. My usage is few times per minute.
Thank you for any information.
Do you use a unique user agent which identifies your application? Nominatim Usage Policy (aka Geocoding Policy)

Thank you for advice. Unfortunatly it didn’t help. Added Referer to communications header, and it didnt helped. Still many of request ending with response Acces Blocked. Any other advise?
You can pay a company money to run Nominatim for you. See the list of service providers on the OSM wiki for further information.

Maybe someone from the same network is overusing free Nominatim servers and it affect also you?
This cannot be my situation, because my project is running on different servers with different networks.
With my next experiment I found one weird behavior. From explorer its always returning correct answer, but using script it sometimes (1/3) return Access blocked. But previous request is few minutes before and that ened correctly.
