No longer able to connect to my various servers with sourcetree
Asked by ccburns:

Until today I have been able to connect to multiple git servers (github, bitbucket, 2 private installs of gitlab) using different public keys.

Today when I tried to push code to these sources I am being rejected due to public key issues.

I ran some experiments with a colleague this morning when the issue first occurred. I'll copy some of the test output below.

```

```

It seems as though the git repository is now looking for id_rsa rather than than the key sample_gitlab which it had been using. I exclusively use sourcetree (rarely resorting to the commandline) to manage my repos so I wonder if this is something to do with the new update???  

If I run the command through ssh-agent it works fine.  

```
ssh-agent $(ssh-add ~/.ssh/sample_gitlab; git push -u origin master)
```

To solve this I ran the following command

```
cp ~/.ssh/sample_gitlab ~/.ssh/id_rsa
cp ~/.ssh/sample_gitlab.pub ~/.ssh/id_rsa.pub
```

Which solves things for connecting to the Sample Gitlab repo but I'm now unable to push/pull from my Bitbucket repositories.  

Any help is appreciated.

Regards,  
Colin

body: Hi Colin,

One thing that stands out to me is that you have a Gitlab and a Bitbucket repo and you're trying to use the same key for both.

At this point I would generate a new key and upload it to BitBucket and see if you're good to go at that point.

Cheers,

Branden

comments: author: ccburns
body: Ok I'll give it a go - thanks  

I did have separate keys for each different server (gitlab, bitbucket) and I didn't have an id_rsa.pub file.  

So not sure what changed to cause this...

I'll try your suggestion.

<br />

Cheers,

Colin
