Please describe the problem.

Trying to copy annexed files to an lfs server via the configured http schemed url results in an error of this form:

$ git-annex copy -t lfsonly
copy mod_access_compat.so (HttpExceptionRequest Request {
  host                 = "computer-ubul.local"
  port                 = 5965
  secure               = True
  requestHeaders       = [("Accept","application/vnd.git-lfs+json"),("Content-Type","application/vnd.git-lfs+json"),("User-Agent","git-annex/10.20241031-1~ndall+1")]
  path                 = ".git/info/lfs/objects/batch"
  queryString          = ""
  method               = "POST"
  proxy                = Nothing
  rawBody              = False
  redirectCount        = 10
  responseTimeout      = ResponseTimeoutDefault
  requestVersion       = HTTP/1.1
  proxySecureMode      = ProxySecureWithConnect
}
 (InternalException (HandshakeFailed (Error_Packet_Parsing "Failed reading: invalid header type: 72\nFrom:\theader\n\n")))) failed
copy mod_autoindex.so (HttpExceptionRequest Request {
  host                 = "computer-ubul.local"
  port                 = 5965
  secure               = True
  requestHeaders       = [("Accept","application/vnd.git-lfs+json"),("Content-Type","application/vnd.git-lfs+json"),("User-Agent","git-annex/10.20241031-1~ndall+1")]
  path                 = ".git/info/lfs/objects/batch"
  queryString          = ""
  method               = "POST"
  proxy                = Nothing
  rawBody              = False
  redirectCount        = 10
  responseTimeout      = ResponseTimeoutDefault
  requestVersion       = HTTP/1.1
  proxySecureMode      = ProxySecureWithConnect
}
 (InternalException (HandshakeFailed (Error_Packet_Parsing "Failed reading: invalid header type: 72\nFrom:\theader\n\n")))) failed
copy: 2 failed

From what I can see, there is no way to work around this. Unlike, for example, the S3 special remotes, initremote doesn't take a protocol=http setting.

What steps will reproduce the problem?

$ git-annex initremote lfsonly type=git-lfs encryption=none url=http://computer-ubul.local:5965/
initremote lfsonly ok
(recording state in git...)
$ git config annex.security.allowed-ip-addresses 172.17.0.1 # required to overcome ConnectionRestricted error
$ git-annex copy -t lfsonly
... eror from above

What version of git-annex are you using? On what operating system?

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Love git-annex. Long time supporter.
