Using HTTPS

Why Use Encryption?

If you install PhotoPrism on a shared server so that it is not only accessible to the local host, always secure the connection using HTTPS. Your files and passwords will otherwise be transmitted in clear text and can be intercepted by anyone, including your provider, hackers, and governments. Backup tools and file synchronization apps may also refuse to connect.

How To Enable HTTPS

You have the following options to enable HTTPS/TLS when using our latest stable release. Note that after adding or updating certificates, it is required to restart PhotoPrism for the changes to take effect.

1. HTTPS Reverse Proxy

To run your instance behind an HTTPS reverse proxy like Traefik, we recommend that you explicitly disable TLS in PhotoPrism by setting PHOTOPRISM_DISABLE_TLS to "true" in your docker-compose.yml configuration:

services:
  photoprism:
    # ...
    environment:
      PHOTOPRISM_SITE_URL: "https://www.example.com/"
      PHOTOPRISM_DISABLE_TLS: "true"

2. Self-Signed Certificate

services:
  photoprism:
    # ...
    environment:
      PHOTOPRISM_SITE_URL: "https://www.example.com/"
      PHOTOPRISM_DISABLE_TLS: "false"
      PHOTOPRISM_DEFAULT_TLS: "true"
      PHOTOPRISM_INIT: "https"

3. Custom Certificate

To use your own certificates, you can add a custom TLS certificate and private key to the storage/config/certificates folder with the filenames www.example.com.crt and www.example.com.key, replacing www.example.com with the actual server domain. For this, you can set the same config options as when using a self-signed certificate (see above).

Alternatively, you can specify a custom TLS certificate (*.crt) and private key (*.key) filename within the storage/config/certificates folder using the PHOTOPRISM_TLS_CERT and PHOTOPRISM_TLS_KEY environment variables in your docker-compose.yml, or use the corresponding command flags:

services:
  photoprism:
    # ...
    environment:
      PHOTOPRISM_SITE_URL: "https://www.example.com/"
      PHOTOPRISM_TLS_CERT: "site.crt"
      PHOTOPRISM_TLS_KEY: "site.key"
      PHOTOPRISM_DISABLE_TLS: "false"
      PHOTOPRISM_DEFAULT_TLS: "true"
      PHOTOPRISM_INIT: "https"

Obtaining Certificates

Valid server certificates can be obtained either from a commercial Certificate Authority (CA) like ZeroSSL or free of charge from Let's Encrypt:

Let’s Encrypt

Let's Encrypt is an automatic certificate authority that provides you with free HTTPS/TLS certificates. Many web servers and reverse proxies such as Traefik and Caddy have integrated support for obtaining single-domain certificates if your server is accessible on port 80 over the public Internet.

The creation of certificates for servers that are not publicly reachable or that are valid for all subdomains (wildcard) is alternatively possible with the LEGO Let's Encrypt client. If you use Docker and DigitalOcean's free DNS service, the command to run will look as follows (replace the certificate path, access token, domain names, and email address with the appropriate values):

docker run --rm -v "/path/to/certificates:/data/" \
-e DO_AUTH_TOKEN=Your_Access_Token goacme/lego -a \
-d "example.com" -d "*.example.com" --email="you@example.com" \
--dns=digitalocean --dns-timeout=180 --path=/data run 

Note that this verification method only works if you use a supported DNS provider that LEGO can access through an API. Please refer to its documentation for details, as each provider requires different authentication credentials. If you are using DigitalOcean, you can create the required access token in your customer dashboard and replace Your_Access_Token with it.

ZeroSSL

ZeroSSL is a widely trusted commercial certificate authority with more than 500,000 customers worldwide. Its headquarters are located in Vienna, Austria.

Compared to Let's Encrypt, you can also create and revoke certificates through a user-friendly web interface, obtain certificates with a validity of more than 90 days, and choose between additional domain verification methods.¹

Troubleshooting

Enabling Trace Log Mode

A good way to troubleshoot configuration issues is to increase the log level. To enable trace log mode, set PHOTOPRISM_LOG_LEVEL to "trace" in the environment: section of the photoprism service (or use the --trace flag when running the photoprism command directly):

services:
  photoprism:
    environment:
      PHOTOPRISM_LOG_LEVEL: "trace"
      ...

Then restart all services for your changes to take effect:

docker compose stop
docker compose up -d

Viewing Docker Service Logs

You can run this command to check the server logs for warnings and errors, including the last 100 messages (omit --tail=100 to see them all, and -f to output only the last logs without watching them):

docker compose logs -f --tail=100

Failed to Find Any PEM Data in Key Input

This error can indicate that your key file starts with an unexpected Byte Order Mark (BOM):

• https://www.google.com/search?q=failed+to+find+any+pem+data+tls+golang
• https://stackoverflow.com/questions/57596920/failed-to-find-any-pem-data-in-key

While BOMs are not strictly forbidden, there is only one way to encode UTF-8, and so they are not needed and extremely rare. As a result, a lot of software has problems with them.

You should be able to fix this by opening the file with a regular text or code editor (not Notepad) and then saving it again. Finally, restart all services for the changes to take effect:

docker compose stop
docker compose up -d
