Unable to upload to S3 bucket

Hello,

I have not been able to upload a file to an S3 bucket for a file of around 120GB. It used to work, but not anymore. Whenever I try, the transfer stops in the middle, very close to the end, with the following error:

upload failed: ../home/cebim/backup_local/comamigo_20240504.sql to s3://clinisul/comamigo_20240504.sql Could not connect to the endpoint URL: "https://clinisul.s3.sa-east-1.amazonaws.com/comamigo_20240504.sql?uploadId=SVTYNY3Ugrkj58gKIdDmzHA.FYRDzeNmT7Wv2O5l8HKXAB2cDFsUA5BZw_F4aQPtqnoHHlD.KBX7GeJpQuFLDG_yywxoewWIf_P96fexyW3NRs5aonmn0SZm5onZ5hqe&partNumber=6261"

I've already tried setting the "max_concurrent_requests" variable to 1, without success. I've already tried specifying the region in the command, but that didn't work either. I imagined that the Internet provider was blocking the connection due to the default being 10 simultaneous requests, but it didn't solve the problem. I have another client that I send a 35GB file that works, but the Internet provider is other. Can anyone shed some light on this?

Thanks.
