Can't reach ollama => /ollama/api/api/tags

[benjaminantunes]

Hi,

I have a dumb trouble since I pulled newest update of open webui today (but i'm not sure the problem comes from this)

I can't reach Ollama because, inside the get request, there is two /api instead of one :

INFO: 192.168.186.21:50946 - "GET /openai/api/models HTTP/1.1" 200 OK
INFO: 192.168.186.21:50946 - "GET /litellm/api/v1/models HTTP/1.1" 200 OK
INFO: 192.168.186.21:50946 - "GET /api/v1/chats/tags/all HTTP/1.1" 200 OK
INFO: 192.168.186.21:50956 - "GET /static/favicon.png HTTP/1.1" 200 OK
INFO: 192.168.186.21:50946 - "GET /ollama/api/api/tags HTTP/1.1" 500 Internal Server Error

In web browser console :
Ollama: 404 Client Error: Not Found for url: http://localhost:11434/api/api/tags

However, I have inspected :

ollamawebui/config.py : The base URL is fine ...
OLLAMA_API_BASE_URL = os.environ.get(
"OLLAMA_API_BASE_URL", "http://localhost:11434/api"
)
OLLAMA_BASE_URL = os.environ.get("OLLAMA_BASE_URL", "http://localhost:11434")

I also looked inside ollamawebui/backend/apps/ollama/main.py :

async def fetch_url(url):
print("URL we are fetching : " + str(url))
try:
async with aiohttp.ClientSession() as session:
async with session.get(url) as response:
return await response.json()
except Exception as e:
# Handle connection error here
print(f"Connection error: {e}")
return None

The url is the right one !! : http://localhost:11434/api/tags

So, I don't understand where it is adding one /api ...
Of course, http://localhost:11434/api/tags is working, but not http://localhost:11434/api/api/tags for clear reasons.

The /api addition is happenning only for /ollama endpoints, in other cases it is fine. In my opinion, this should come from OLLAMA_BASE_URL, but looks like it is not coming from there ...

Getting stuck on such a dumb thing is quite annoying, thank you for your help !

Try updating again just to be sure you've got the lastest version, and change the OLLAMA_API_BASE_URL=http://localhost:11434/api to OLLAMA_BASE_URL=http://localhost:11434 instead, note that the name of the variable has changed and we no longer put /api on the end of the URL.

I just started again from zero, creating a new folder, and it is working.
I can't figure out why it was working, then git pull, and then had this problem.

But starting from scratch solved the problem !
Thank you for your answer

You might also want to delete your browser cache just in case!

Thank you, I tried but can't figure out what was the problem. Starting from scratch solved it.
