+## [SSL: CERTIFICATE_VERIFY_FAILED]
+
+If you get this error while trying to run OI, most likely the issue is that you are on a network which intercepts HTTPS traffic (e.g. a corporate network), 
+you will need to add the new cert into OI's truststore. 
+
+**For pre-built Docker image**:
+
+1. Mount the certificiate store from your host machine into the container by passing `--volume=/etc/ssl/certs/ca-certificiate.crt:/etc/ssl/certs/ca-certificiates.crt:ro` as a command-line option to `docker run`
+2. Force python to use the system truststore by setting `REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt` (see https://docs.docker.com/reference/cli/docker/container/run/#env)
+
+Example `compose.yaml` from [@KizzyCode](https://github.com/open-webui/open-webui/issues/1398#issuecomment-2258463210):
+
+```yaml
+services:
+  openwebui:
+    image: ghcr.io/open-webui/open-webui:main
+    volumes:
+      - /var/containers/openwebui:/app/backend/data:rw
+      - /etc/containers/openwebui/compusrv.crt:/etc/ssl/certs/ca-certificates.crt:ro
+      - /etc/timezone:/etc/timezone:ro
+      - /etc/localtime:/etc/localtime:ro
+    environment:
+      - WEBUI_NAME=compusrv
+      - ENABLE_SIGNUP=False
+      - ENABLE_COMMUNITY_SHARING=False
+      - WEBUI_SESSION_COOKIE_SAME_SITE=strict
+      - WEBUI_SESSION_COOKIE_SECURE=True
+      - ENABLE_OLLAMA_API=False
+      - REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
+```
+
+**For local development**:
+
+You can also add the certificates in the build process by modifying the `Dockerfile`. This is useful if you want to make changes to the UI, for instance.
+Since the build happens in [multiple stages](https://docs.docker.com/build/building/multi-stage/), you have to add the cert into both
+1. Frontend (`build` stage): 
+```dockerfile
+COPY package.json package-lock.json <YourRootCert>.crt ./
+ENV NODE_EXTRA_CA_CERTS=/app/<YourRootCert>.crt
+RUN npm ci
+```
+2. Backend (`base` stage):
+```dockerfile
+COPY <CorporateSSL.crt> /usr/local/share/ca-certificates/
+RUN update-ca-certificates
+ENV PIP_CERT=/etc/ssl/certs/ca-certificates.crt \
+    REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
+```
