Tryton - Login, Could not connect to the server

Support System Administrator
1

I had this error before I reinstalled ubuntu 22, tryton, trytond and postgres.

pip install trytond==6.4.16
pip install tryton==6.4.12

After fresh install still getting the error:
Could not connect to the server

Thanks

I think you need to provide more details in order to receive help.

I think it is better to tell what you have rather than what you had?

Trytond is a daemon (server) that needs to be running in order for tryton (client) to be able to connect to it.

How is trytond started?

If you provide logs from trytond, either a log file, or copy stdout if you are running trytond on the commandline.
Frankly, when testing I find it most useful to run trytond on the commandline so that I can see easily what trytond is doing.

@awes7 Austin,
try this basic trytond.conf instead:

[database]
uri = postgresql://postgres:postgres@localhost/

Hi thanks, but still get an error:

(.my_env8) awes7@viion:~/projects/training8$ tryton
ERROR:tryton.rpc:502
ERROR:tryton.rpc:500

When connect tryton make sure that you connect to localhost:

tryton -s localhost

and trytond using the config file:

trytond -c trytond.conf

(.my_env8) awes7@viion:~/projects/training8$ tryton -s localhost
ERROR:tryton.rpc:502
ERROR:tryton.rpc:500

Maybe you have got some trytond-something modules missing on your my_env8
try:
trytond-console -c trytond.conf -d training8

If your get an error about FileNotFoundError: …site-packages/trytond/modules/something/tryton.cfg then, installed using pip and try again the trytond-console

(.my_env8) awes7@viion:~/projects/training8$ trytond-console -c trytond.conf -d training8

You always show the output of tryton, but never the output of trytond.
Does trytond indicate a successful start from the logs/stdout?

Make sure localhost points to localhost address(127.0.0.1). A decade ago I spent almost a day troubleshooting a connection issue, and localhost was redefined to some other address. Or try to connect to 127.0.0.1 instead.

When you get ERROR:tryton.rpc:502, do you also get the corresponding output line from trytond?

I think you get that error on the client when you click on Manage… as it tries to connect to demo6.4.tryton.org

try the 6.6 branch:

pip uninstall trytond tryton -y
pip install tryton==6.6.11 trytond==6.6.13

thank you very much that worked. Unfortunately, I wanted to use version 6.4 because I was using this us chart of accounts. GitHub - pentandra/account_us: tryton account_us module

I was able to get the us chart to work with 6.6, thanks.
