Anyone has an idea what I might be doing wrong? After running “docker-compose up”, I get the following: ``` stack_1 | INFO Setting up Identity Server stack_1 | error:cmd/internal/shared:initialize_identity_server (could not initialize Identity Server) stack_1 | --- parse "postgres://root@cockroach:26257/ttn_lorawan?sslmode=disable": first path segment in URL cannot contain colon ttn_stack_1 exited with code 255 ``` I went ahead and edited “postgres://root@cockroach:26257/ttn\_lorawan?sslmode=disable” in docker-compose.yml and removed the first colon: “postgres//root@cockroach:26257/ttn\_lorawan?sslmode=disable” Although that error doesn’t make sense to me, I now got a different error after removing the colons: ``` stack_1 | INFO Setting up Identity Server stack_1 | error:cmd/internal/shared:initialize_identity_server (could not initialize Identity Server) stack_1 | --- dial tcp: lookup postgres on 127.0.0.11:53: server misbehaving ttn_stack_1 exited with code 255 ``` I am running everything in an Ubuntu Bionic VM on localhost or 127.0.0.1 Thanks in advance! ---

I also saw this error when removing the colons only as above: ``` stack_1 | INFO Setting up Identity Server stack_1 | error:cmd/internal/shared:initialize_identity_server (could not initialize Identity Server) stack_1 | --- dial tcp 127.0.0.1:5432: connect: connection refused ``` As far as I understand, port 5432 should only be available if I use the Postgres DB instead of CockroachDB. I am only using CockroachDB per the default configuration so I don’t understand why it’s trying to connect to port 5432. Maybe because CockroachDB URL became wrong after I removed the colons so now it’s falling back to postgres? ---

Hello Zaher I see in your post you mentiond that yo use Localhost 127.0.0.1 but in the screen you send you use “lookup postgres on 127.0.0.11” I hope it is this typo for you 🙂 > [@zaher](#): > > ```auto > stack_1 | INFO Setting up Identity Server > stack_1 | error:cmd/internal/shared:initialize_identity_server (could not initialize Identity Server) > stack_1 | --- dial tcp: lookup postgres on 127.0.0.11:53: server misbehaving > ttn_stack_1 exited with code 255 > > ``` > > I am running everything in an Ubuntu Bionic VM on localhost or 127.0.0.1 ---

Hi @jwijngaard - thanks for replying! Actually, the error you mentioned I have seen only once when I accidentally removed both cockroach and postgres from the yml file, which is still weird and sounds to me like a bug in the container. However, if you look at the other two errors I listed, they correctly mention the IP address 127.0.0.1 So unfortunately the problem I mentioned earlier persist ☹ ---

I switched from using CockroachDB to using Postgres instead, and now I am seeing a different error: ``` stack_1 | INFO Setting up Identity Server stack_1 | error:cmd/internal/shared:initialize_identity_server (could not initialize Identity Server) stack_1 | --- error:pkg/identityserver:db_needs_migration (the database needs to be migrated) stack_1 | --- error:pkg/identityserver/store:database_table (database table `accounts` does not exist) stack_1 | table=accounts ttn_stack_1 exited with code 255 ``` I also noticed this in the logs which could be relevant: ``` postgres_1 | 2020-01-10 01:22:10.011 UTC [23] LOG: database system was shut down at 2020-01-09 23:24:35 UTC postgres_1 | 2020-01-10 01:22:10.024 UTC [1] LOG: database system is ready to accept connections ``` ---

Hi Zaher, I got your same error. I solved following instructions on [https://thethingsstack.io/v3.3.2/guides/getting-started/running-the-stack/](https://thethingsstack.io/v3.3.2/guides/getting-started/running-the-stack/) I initialized tables in cockroach, created admin user and so on… In this way web server is up and running. ---

@carlomissaglia, thanks very much for helping! I ran `docker-compose pull` and it seems to have worked just fine: ``` Pulling cockroach ... done Pulling redis ... done Pulling stack ... done ``` However, after I run: `docker-compose run --rm stack is-db init` I still see the following error: ``` Starting ttn-stack_redis_1 ... done Starting ttn-stack_cockroach_1 ... done INFO Connecting to Identity Server database... parse "postgres://root@cockroach:26257/ttn_lorawan?sslmode=disable": first path segment in URL cannot contain colon ``` ---

Hi zaher, You have to delete “ at the begin and at the end. Try in this way. postgres://root@cockroach:26257/ttn\_lorawan?sslmode=disable BR. ---

That was exactly my issue! Thanks a lot @carlomissaglia! I was able to run without errors unitl `docker-compose up`, I got the following error: ``` stack_1 | --- error:pkg/gatewayserver:listen_frontend (failed to start frontend listener `MQTT/tls` on address `:8882`) stack_1 | address=:8882 stack_1 | protocol=MQTT/tls stack_1 | --- open cert.pem: no such file or directory ``` I know the cert.pem file exists in the same directory where I have `docker-compose.yml` and run the `docker-compose up` command from. I also made sure I have run `chown 866:866 ./cert.pem`. Even when I changed it to an absolute file path in the `docker-compose.yml`, I still got the same error. What could I be missing here? ---
