# SourceCommit troubleshooting

Available in Classic and VPC

You might run into the following problems when using SourceCommit. Find out causes and possible solutions.

## Error message: "The requested URL returned error: 403"

I received the message "The requested URL returned error: 403."

#### Cause

This error occurs when the credentials are not issued or the authentication information is not valid.

#### Solution

See [Using Git client](/docs/en/sourcecommit-use-client) and issue the proper credentials for the access method (HTTPS/SSH) or check the authentication information again.

## Cannot copy external repository

This error occurs even when I enter the Github URL, ID, and password correctly to copy an external repository.

#### Cause

Github does not allow authentication through password. It allows Token authentication method only.

#### Solution

As for Github, you need to enter the ID and token value to copy an external repository, not the ID and password. See [https://github.com/settings/tokens](https://github.com/settings/tokens) to create a token and check related permissions (contents).

## Error when uploading large project

An error occurs when I upload a large project.

#### Cause

The file size you can upload to Git repository is limited to 500 MB.

#### Solution

- Use Git Large File System (LFS). Git LFS performs by committing only metadata of large files into the repository and storing the actual content in the extra remote storage. For more information, see [Upload large files](/docs/en/sourcecommit-use-lfs).
- Instead of committing all files at once, try to divide them into small units to commit and push.

## Permission error

A permission error occurs. "Permission denied (publickey)." error message is displayed.

#### Cause

This problem occurs when SSH key settings are incorrect.

#### Solution

- Check if the public key registered to SourceCommit matches the IdentityFile in config.
- Check if the Git SSH access settings are correct.

## 403 error after resetting Git account

After resetting the Git account, the 403 error occurs when I run `git clone`.

#### Cause

This problem may occur if there is remaining existing authentication information.

#### Solution

To initialize the authentication information (credential.helper) in Git config depending on the Git setup range, follow these steps:

- Initialize the current Git project settings

```
git config --local --unset credential.helper
```
- Initialize the logged-in user settings

```
git config --global --unset credential.helper
```
- Initialize system settings

```
git config --system --unset credential.helper
```
