Hi I’m running defold on Linux, the problem is variable DM\_SERVICE\_PORT is ignored when opening the editor I’ve set `export DM_SERVICE_PORT=8001`. But when running the editor, the editor still runs on random port ```lua util.http-server - {:line 376, :msg "Http server running", :local-url "http://localhost:44085"} ``` Because of firewall i need the editor to keep using the same port. Is there any other way to set the http port? Thank you ---

That’s correct, DM\_SERVICE\_PORT is ignored in that case ([defold/engine/docs/DEBUG\_PORTS\_AND\_SERVICES.md at dev · defold/defold · GitHub](https://github.com/defold/defold/blob/dev/engine/docs/DEBUG_PORTS_AND_SERVICES.md)). It’s a bit silly to be honest and I think it’s something we should change. Can you please open a feature request on GitHub? ---

Hi! I currently have the same problem with Defold [v1.12.4](https://github.com/defold/defold/releases/tag/1.12.4). I’m using Kubuntu 24.04. When I try to run Defold (standalone executable) from terminal with `DM_SERVICE_PORT=8001 ./Defold` or with `export DM_SERVICE_PORT=8001` + `./Defold`, the editor still runs in random port: ```lua util.http-server - {:line 380, :msg "Http server running", :local-url "http://localhost:41785"} ``` Is there still something that I’m missing? Or should I create a new issue ticket? I saw that the previous issue was fixed by [Check ENV and validate DM\_SERVICE\_PORT by JosephFerano · Pull Request #11407 · defold/defold · GitHub](https://github.com/defold/defold/pull/11407). But I have still the issue in v1.12.4. I also tested [v1.11.2](https://github.com/defold/defold/releases/tag/1.11.2) and [v1.12.0](https://github.com/defold/defold/releases/tag/1.12.0) but the issue reproduces also in these. ---

For the record if someone has the same issue I had: `--port` argument seems to work and changes the port of the HTTP server (documented in here: [Automating the Defold editor with HTTP](https://defold.com/manuals/editor-http-api/#starting-the-editor-from-an-external-tool)). For example, running `./Defold --port 7777` works for me and the port is changed to 7777. Maybe `DM_SERVICE_PORT` is not correct parameter in my use case.
