I meet an error I don't understand. On the 30/09/2021 on branch dev at commit [60eb5d](https://git.duniter.org/clients/python/silkaj/-/commit/60eb5dc2d80485d8ff7df777a52ab361a1e92c12). On Linux Mint 20.1 Ulyssa I can reach nodes. `silkaj info` works. However, `silkaj blocks` does not : ```python $ silkaj blocks Traceback (most recent call last): File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/bin/silkaj", line 5, in <module> cli() File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/click/core.py", line 1134, in __call__ return self.main(*args, **kwargs) File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/click/core.py", line 1059, in main rv = self.invoke(ctx) File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/click/core.py", line 1665, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/click/core.py", line 1401, in invoke return ctx.invoke(self.callback, **ctx.params) File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/click/core.py", line 767, in invoke return __callback(*args, **kwargs) File "/home/thomas/Documents/Duniter/silkaj/silkaj/commands.py", line 159, in list_blocks idty = identity_of(issuer["pubkey"]) File "/home/thomas/Documents/Duniter/silkaj/silkaj/wot_tools.py", line 33, in identity_of return client(wot.identity_of, pubkey_uid) File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/duniterpy/api/client.py", line 455, in __call__ return _function(self, *args, **kwargs) File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/duniterpy/api/bma/wot.py", line 350, in identity_of return client.get(MODULE + "/identity-of/%s" % search, schema=IDENTITY_OF_SCHEMA) File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/duniterpy/api/client.py", line 372, in get return client.request_url( File "/home/thomas/.cache/pypoetry/virtualenvs/silkaj-hneDEFxq-py3.8/lib/python3.8/site-packages/duniterpy/api/client.py", line 260, in request_url with request.urlopen( File "/usr/lib/python3.8/urllib/request.py", line 222, in urlopen return opener.open(url, data, timeout) File "/usr/lib/python3.8/urllib/request.py", line 531, in open response = meth(req, response) File "/usr/lib/python3.8/urllib/request.py", line 640, in http_response response = self.parent.error( File "/usr/lib/python3.8/urllib/request.py", line 569, in error return self._call_chain(*args) File "/usr/lib/python3.8/urllib/request.py", line 502, in _call_chain result = func(*args) File "/usr/lib/python3.8/urllib/request.py", line 649, in http_error_default raise HTTPError(req.full_url, code, msg, hdrs, fp) urllib.error.HTTPError: HTTP Error 503: Service Unavailable ```
