> I think I’ve added the sourceror successfully, however, I still got the error message Yes you did, however there’s quite a number of warnings as well as you can see. From the sourceror README it reads that they DO support your version of Elixir and OTP, but as a first poke you could try installing fresher versions of each via [ASDF package manager](https://asdf-vm.com/guide/getting-started.html) (very convenient and supports a lot of tools other than Elixir/OTP). After removing your old installations of Elixir and Erlang and installing ASDF following the instructions on their website: ```elixir asdf plugin-add elixir asdf plugin-add erlang asdf install erlang 25.3 asdf install elixir 1.14.4-otp-25 asdf global erlang 25.3 asdf global elixir 1.14.4-otp-25 ``` --- _[View the full topic](https://forum.elixirforum.com/t/elixirls-server-initialization-failed/55460)._
