ERROR connecting to Git: Cannot Open git-upload-pack

[Anonymous]

Hello Experts,

We have been working on the Enterprise edition of 6.5.1 (latest) at my work and have been given a Studio package. All the git, TAC, Job Server are set-up. 

I get intermittent issues while logging into the Talend Studio. Sometimes it works, sometimes it doesn't.

Have worked with the Talend consultant on premises but with no luck.

Does anyone have an actual trouble shoot guide for connectivity issues between Git and TAC?

Are there any know issues with 6.5.1 (Big Data Edition) anyone aware of?

Please advise.

Hello,

With your Enterprise edition of 6.5.1,  have you already created a case on talend support portal? In this way, we will give you a remote assistance by webex session to see if a jira issue need to be raised on talend bug tracker.

Best regards

Sabrina

It is easy to test it. I entre the server TAC by remote a computor and start git url. it does not work.

So, you can check it firstly

Hello @natty

Did you configure git username & password in TAC? Is Git client is installed on your machine? Is Git config user.name and email set already?

Here exists a related jira issue:https://jira.talendforge.org/browse/TUP-18028 and it has been fixed on V 6.4.1

Best regards

Sabrina

[lopez9117]

i had the same issue and the solution was change my talend version from 7.2 to 7.1

[Girish1]

Hi, We are using Talend 7.2.1 and I am also facing the similar issue while connecting to project in GitHub, I saw the comment on reverting to 7.1, is there any bug in 7.2.1 ? or is there any workaround to sort this in 7.2.1.

We have added the project in TAC and we can see the branches and tags in TAC, but facing error when we are trying to connect to the project from studio.

Any help or link where we have solution for the same would be really helpful and appreciated. Thanks.
